00:00 Welcome to WatchMojo, and today we're counting down 200 facts that might save your life one day.
00:07 If you have a potentially life-saving fact, drop it in the comments, and we can all learn together.
00:15 Cold conditions can be deadly.
00:18 Symptoms of mild hypothermia include shivering and mental confusion.
00:22 In moderate cases, shivering stops.
00:25 Severe cases can include hallucinations and paradoxical undressing.
00:30 Get warm and seek immediate medical treatment.
00:33 If you're trying to carry out a rescue, there's a chance you yourself could become in need of rescuing.
00:40 Prioritize your own safety and check for danger when attempting a rescue.
00:45 Untrained first responders risk becoming casualties themselves, especially in urgent situations.
00:52 A flu vaccine uses a deactivated or weakened version of the virus to train your body to recognize it.
01:00 This allows your immune system to develop antibodies and fight the flu better when you actually catch it.
01:06 Influenza or the flu isn't something to be sniffed at.
01:11 You are more likely to survive choking on something if you have people around you to help.
01:17 So if you're choking, don't get embarrassed and walk away from people.
01:21 Instead, perform the universal sign of choking with both hands on your neck.
01:26 And others around you should realize what's going on.
01:29 Most venomous snakes have thin, cat-like pupils, while non-venomous snakes have round pupils.
01:40 However, there are exceptions, like the venomous coral snake.
01:45 Solid-colored snakes are often non-venomous, whereas colorful ones are typically venomous.
01:52 If you're in a forest and there's a moment of sudden silence, pause and listen attentively.
01:58 The silence could indicate the presence of a predator nearby.
02:02 Remain vigilant and be aware of your surroundings.
02:07 Campfires can repel wild animals since they signal where humans are.
02:12 However, bears aren't repelled by campfires and can instead use them as a beacon to wander into camp.
02:20 Be aware of your surroundings and whether or not making a fire is the best idea for your situation.
02:26 Africanized bees, also known as killer bees, are more aggressive than other bee species
02:33 and can swarm and attack humans if disturbed.
02:37 They also chase people further, up to a quarter-mile, than other varieties of honeybees.
02:43 If someone faints, don't keep them upright.
02:47 Blood drops down into the legs when upright, reducing the amount of blood returning to the heart,
02:52 leading to decreased pumping ability and lowered blood pressure.
02:56 Instead, gently catch them and lay them down in recovery as soon as possible.
03:02 Fainting occurs when the brain requires more blood to function properly,
03:06 so keeping the person standing can exacerbate the situation.
03:09 Boredom could be slowly killing you.
03:19 Studies have shown that boredom is linked to depression, anxiety, stress,
03:24 and unhealthy lifestyle choices.
03:26 The opposite of burnout at work is known as bore-out.
03:31 One well-placed head or misplaced step can lead to fatal injury in any fight.
03:38 No conflict is better than winning a conflict,
03:41 as even a brief fight can have disastrous consequences.
03:45 So de-escalate a situation if you can.
03:48 If there's no preventing a physical altercation, fight dirty.
03:52 Go for the groin, eyes, or ears.
03:55 While this might seem obvious to some,
03:58 texting or calling while driving is incredibly dangerous.
04:02 The same goes for eating and drinking while driving.
04:05 When you try to multitask like this, it can cause inattentional blindness,
04:10 where you fail to perceive fully visible objects.
04:14 This can lead to fatal accidents.
04:16 Don't grab a dog's collar when breaking up a dog fight,
04:20 as this might cause them to bite you.
04:23 Instead, lift the dog's back legs under the hip like a wheelbarrow
04:28 and move backward, away from the other dog.
04:31 While most minor animal bites are not serious,
04:35 some lead to a life-threatening infection.
04:37 This includes bites from domestic and wild animals.
04:41 Clean the wound with soap and water,
04:43 apply antibiotic cream, and cover the wound with a clean dressing.
04:48 Seek urgent medical care if the wound is swollen, painful, or leaking fluid.
04:53 Landslides and rock slides can be deadly.
04:57 If you're caught in one, move quickly away,
04:59 find cover, and shield your head using your arms to avoid getting hit by falling debris.
05:05 Green potatoes are toxic to humans.
05:09 Potatoes become green when exposed to sunlight, causing the production of solanine.
05:14 Eating them can cause symptoms such as nausea, headache, and in severe cases, even death.
05:20 In case you're not freaked out enough,
05:22 the part above the plant, you know, that grows above ground that contains leaves and stems,
05:25 it also grows these cute little berries.
05:27 Don't eat those berries!
05:28 Those little guys contain 10 to 20 times the glycoalkaloid, and they will lay you out.
05:33 If your clothes catch fire, you will get burnt.
05:36 So before it does too much damage, remember, stop moving, drop to the ground,
05:42 covering your face with your hands, and roll to extinguish the fire by depriving it of oxygen.
05:48 If you're stuck out at sea, do not drink seawater.
05:53 The salt in the seawater will dehydrate you faster than the water will hydrate you,
05:59 bringing you even closer to death.
06:02 Don't you know the poem, "Water, water everywhere, so let's all have a drink"?
06:06 Homer, no!
06:08 Tornadoes rip through the higher floors of buildings, so if you're caught up in one,
06:14 go to the lowest room inside, ideally without windows, preferably the basement.
06:19 But ensure you don't take shelter where heavy objects would be directly above you.
06:25 It can be hard to spot people from the air, so if you find yourself in the wilderness
06:29 and need to signal to an aircraft for help,
06:32 use a mirror or reflective object to flash sunlight and attract attention.
06:37 Speaking of being lost in the wilderness, if you are lost and think you'll be there for a while,
06:43 your first step should be to find shelter and water.
06:46 The first thing to kill you could be hypothermia.
06:49 Some species of fish are poisonous to humans.
06:53 Improper preparation of certain fish like the pufferfish or fugu can lead to paralysis and even death.
07:01 Domoic acid, a toxin produced by specific types of algae,
07:05 can cause seizures and fatal consequences upon consumption of contaminated seafood.
07:12 It typically accumulates in shellfish, sardines, and anchovies.
07:16 Found in tide pools in the Indian and Pacific Ocean,
07:21 the blue-ringed octopus produces a neurotoxin that can cause paralysis and death.
07:27 And there is no known antivenom, so stay away!
07:37 Speaking of octopuses or octopi, while it's rare for a giant octopus to attack a human,
07:44 it can be very dangerous if they do.
07:47 If one does grab you, swim away forcefully.
07:50 Don't go limp or let its arms wrap around you, or you'll have difficulty escaping.
07:55 Try to detach it from its anchor so it can't drag you down and head towards the surface.
08:01 They dislike air and will likely let go, but if they don't, peel off those suckers!
08:07 Volcanic ash can be dangerous to breathe in,
08:10 especially if you have conditions like asthma or emphysema.
08:14 Since it's frozen lava, you're basically breathing in glass,
08:19 lacerating your insides and causing potentially permanent scars in your lungs.
08:23 While a filtration mask isn't an absolute solution, it can't hurt to bring one along.
08:29 Radon is a colorless, odorless radioactive gas present in most soil.
08:35 However, it can get trapped in your home, causing a buildup that can lead to lung cancer.
08:41 Symptoms of exposure include shortness of breath, coughing,
08:45 pain or tightness in the chest, and trouble swallowing.
08:48 You can have your home tested by a professional or with a do-it-yourself kit.
08:53 Another odorless and colorless gas that can be dangerous is carbon monoxide,
08:58 which is released by engine exhausts, fireplaces, and appliances that burn wood, gas, oil, or coal.
09:05 The most common symptoms of carbon monoxide poisoning are headache,
09:09 dizziness, weakness, upset stomach, vomiting, chest pain, and confusion.
09:15 If you think you've been exposed, get some fresh air and call emergency services.
09:20 And make sure to change the battery on your carbon monoxide detector!
09:24 Ticks are small, spider-like creatures that feed on the blood of animals.
09:30 They are also carriers of diseases, such as Lyme disease.
09:34 If you're bitten by one, watch for symptoms such as a rash, fever, and fatigue.
09:40 Major earthquakes have rarely ever been predicted, so if you ever find yourself in one,
09:47 drop to your hands and knees so you don't get knocked over.
09:50 Cover your head and neck and get underneath something sturdy like a table or a desk.
09:55 Hold on to whatever shelter you have and be prepared to move with it if it begins to shift around.
10:01 At 8,000 feet or 2,500 meters above sea level, you can suffer from altitude sickness.
10:09 You'll feel like you've got a hangover, headache, puking, dizziness, tiredness,
10:14 no appetite, and breathing troubles.
10:17 When hiking or climbing, ascend slowly, 1,000 feet a day.
10:22 If you suspect you have altitude sickness, stop and rest for at least 24 to 48 hours.
10:28 If you don't feel better, descend to a lower altitude.
10:32 When you have a nosebleed, tilting your head back can cause blood to go down your throat,
10:38 choking you, or irritating your stomach.
10:41 Instead, apply an ice pack to reduce swelling.
10:44 Pinch the nostrils together and lean forward slightly.
10:47 Drowsy driving is extremely dangerous.
10:51 If you're feeling sleepy behind the wheel, pull over,
10:54 let someone else drive, drink coffee, or nap before continuing.
10:59 As a passenger, be aware that you are the fail-safe in this situation,
11:03 and be prepared to wake up a sleeping driver by calling their name or shaking them.
11:09 A bright flashlight can be an effective tool when defending yourself at night.
11:14 Shine a light in an attacker's face, and you can momentarily blind them,
11:18 giving you a chance to escape danger.
11:20 Diet has little influence on the body's detoxification.
11:26 There is no evidence that detoxification diets rid the body of toxins.
11:31 Some of these detox diets can have serious side effects, so be careful and do your research.
11:37 Just because the traffic light is green does not mean you are safe to go.
11:43 Many people still die in car accidents even if they have right-of-way.
11:47 Always keep an eye out for oncoming dangers.
11:50 Financial troubles drastically increase the risk of someone attempting to take their own life.
11:57 Various factors are at play here, including systemic issues,
12:01 but it's important to manage your money carefully to mitigate this problem,
12:05 and look out for friends and family who are experiencing money problems.
12:09 The World Health Organization estimated that dust and household air pollution
12:15 were responsible for 3.2 million deaths per year in 2020.
12:20 Much of this pollution comes from open fires and inefficient stoves, especially in rural areas.
12:26 Try to make sure your home is well-ventilated,
12:29 and avoid kerosene, biomass, and coal as fuel sources.
12:34 That being said, outside, the air isn't so fresh either.
12:38 The World Health Organization estimated that ambient air pollution
12:42 caused 4.2 million premature deaths worldwide in 2019.
12:48 Check air pollution forecasts and support policies for cleaner transport and industry management.
12:55 Jumping in elevators might seem fun, but the impact accumulates unseen damage.
13:02 Roughhousing in one might be the last straw on an already strained system.
13:07 So don't screw about.
13:08 Don't mess with escalators either.
13:14 Escalator accidents have resulted in amputation, strangulation, and even death.
13:20 Carjacks are meant for lifting, not holding.
13:24 So don't go underneath a car that's just supported by a carjack, or you might get crushed.
13:29 Instead, use jack stands, which are inexpensive and readily available.
13:35 When in a desert, you are much more likely to become dehydrated from water loss
13:40 than from lack of access to drinkable water.
13:43 As such, don't overexert yourself.
13:46 Cover your skin, breathe through your nose, seek shade, and avoid drinking diuretic drinks.
13:53 Garbage collecting is one of the deadliest jobs in the United States.
13:58 Hazards in our waste are a problem,
14:00 as are impatient drivers who pass stopped trucks only to hit collectors.
14:05 Slow down and give garbage trucks a wide berth.
14:09 You might feel fine after you hit your head, but the effects of traumatic brain injuries can take time.
14:17 Even if you didn't hit your head that hard, have someone stay with you and seek medical
14:22 attention if you experience headaches, dizziness, drowsiness, nausea, or confusion.
14:28 Holy water has been linked to dangerous infections, rashes, and the spread of diseases.
14:35 Because so many people use church fonts, it becomes a habitat for dangerous bacteria.
14:40 In fact, most holy water is contaminated by fecal matter.
14:46 So do not drink it!
14:48 If your boat is sinking, you are more likely to survive the longer you stay out of water.
14:55 Don't immediately jump out of the boat if it's taking on water.
14:59 Stay on it and try to plug the leak while signaling for help.
15:02 As tempting as it might be to fry up a meal after a few pints,
15:07 cooking while drunk can be pretty dangerous.
15:10 One survey from the UK found people putting cutlery in toasters,
15:14 putting the wrong thing in the microwave, or even leaving the oven door open to warm up the room.
15:21 Some even fell asleep while cooking, leaving an open flame unattended,
15:26 burning their food, and smoking up the house.
15:30 Please be careful.
15:32 Delaying medical treatments or even ignoring symptoms can lead to more severe health problems
15:38 and even death.
15:39 So be sure to get regular checkups with medical professionals.
15:43 You never know what might be wrong.
15:45 Drinking a responsible amount of alcohol with friends is fine.
15:50 But becoming blackout drunk can be incredibly dangerous.
15:54 Memory loss might be the least of your concerns,
15:56 as there is a real danger you could throw up and choke.
16:00 Being so inebriated that you can't look after yourself is never a good look.
16:05 Drink responsibly.
16:07 Even if you've been talking to someone online for a long time,
16:11 you still don't truly know who that person is.
16:15 People can be completely different in person and potentially even dangerous.
16:20 If you plan on meeting up with someone, video call before seeing them,
16:24 meet in a public place, have a reason or excuse to leave shortly after,
16:28 and always tell someone where you are going.
16:32 Poor oral hygiene is linked to heart disease.
16:36 The bacteria that infects the gums can also travel to blood vessels elsewhere in the body,
16:41 where they cause inflammation and damage.
16:44 This can lead to tiny blood clots, a heart attack, or even a stroke.
16:49 A lot of things can fit in your refrigerator.
16:53 Some are even big enough to fit a person.
16:55 You might have even put your friends in there as a joke.
16:58 But this is actually incredibly dangerous.
17:01 There have been cases where people have suffocated to death
17:04 due to the lack of oxygen in refrigerators.
17:07 Most refrigerators also use dangerous, flammable, or toxic chemicals,
17:14 like Freon.
17:15 So don't mess about with a refrigerator, don't breathe in those gases,
17:19 and dispose of appliances safely when you're getting rid of them.
17:24 The CDC estimates that 48 million people get sick from foodborne illnesses each year.
17:32 It can happen more easily than you think.
17:35 Make sure you cook and store your food correctly,
17:38 wash your hands before eating, and don't ignore those expiration dates.
17:44 There is an area on your face between the corners of your mouth
17:47 and the bridge of your nose known as the triangle of death.
17:52 Avoid popping pimples here, as if you get an infection, it can spread to your brain.
17:58 We know it's hard, but just leave those zits alone.
18:09 Inhaling paint or gasoline fumes can happen by mistake when you're painting
18:14 or using gas-powered tools somewhere with bad ventilation.
18:18 You might feel dizzy, get a headache, feel like you're gonna barf, or even pass out.
18:23 Over time, it can damage your brain, liver, kidneys, or other organs.
18:29 So it's important to use the right safety gear,
18:31 take breaks, and avoid working in poorly ventilated indoor spaces.
18:37 Once upon a time, doctors in maternity wards didn't wash their hands between patients.
18:43 A study in the 1840s demonstrated that handwashing dramatically decreased mortalities.
18:50 Now it's common practice, but it proves the importance of washing your hands.
18:54 You never know what might lurk on them, even if they look clean.
18:58 Do you wear a lanyard?
19:01 If so, you might have one that has a breakaway latch.
19:04 These were invented to prevent choking or suffocation accidents.
19:07 But this can also extend to necklaces and jewelry.
19:11 Be careful, as you're wearing something close to a delicate part of your body.
19:15 A tan is your body's way of trying to protect itself from the damaging effects of UV rays.
19:23 Prolonged exposure to UV rays has been linked to malignant melanoma,
19:28 the most serious form of skin cancer.
19:31 Use sunscreen in the sun, and consider whether using a tanning bed is really worth it.
19:36 You'd think that you could hear a train coming from miles away.
19:41 But you can't!
19:42 Trains can come much faster than you think, with minimal warning signs.
19:46 The sound gets bounced off and dampened by obstacles, distorting how far away it seems.
19:52 Don't play on train tracks!
19:54 [Sounds of a train]
20:04 Accidental or negligent weapon discharge can happen even if you don't have your finger on the trigger.
20:11 The lightest pressure, or even a malfunction of the internal mechanism, can cause a firearm to go off.
20:18 Even if you think there isn't a bullet in the chamber,
20:21 don't ever point a weapon at someone unless you absolutely need to use it.
20:26 Otherwise, what might have started as a joke could become deadly.
20:31 You can overdose on over-the-counter medication,
20:35 accounting for a significant proportion of overdose presentations in emergency rooms.
20:41 When someone sprays on too much deodorant, it can be incredibly off-putting.
20:46 But it's worse than you think.
20:48 In the United Kingdom, a 16-year-old was so obsessed with smelling fresh,
20:53 he would cover his entire body in deodorant at least twice daily.
20:57 The gases in his body due to accidental inhalation later caused a fatal heart attack.
21:03 You don't need to bathe in the stuff.
21:05 Garage door springs carry a lot of tension.
21:09 Even if one side is broken, the other could still hold in all that energy.
21:14 And incorrectly replacing one can prove deadly.
21:17 So be sure to hire a professional, or it could be your life on the line.
21:21 Did you know that some states in the US have no safety regulations for amusement parks?
21:29 Some leave it entirely up to the counties,
21:31 with many not being required to record how many injuries or incidents they have had properly.
21:38 Be extra careful the next time you want to go on a ride.
21:42 [Screaming]
21:50 The largest diameter hailstone recorded was bigger than a bowling ball.
21:55 While hailstones that large are rare, it's best to take cover during a hailstorm.
22:01 It's very common for people not to drink enough water.
22:05 But did you know you can also overhydrate?
22:08 When marathon runners drink lots of water, they sometimes add salt to balance out their electrolytes.
22:14 Firing a shot into the air doesn't make the bullet suddenly disappear into space.
22:20 You are responsible for everything that leaves your firearm's barrel and what it hits.
22:26 Out of sight, out of mind doesn't work here.
22:29 You never know where your content or conversations online will end up.
22:35 They can be screenshotted, saved, copied, pasted, and spread to places you wouldn't even think of.
22:41 So before posting something, consider that whatever goes on the internet will stay on it,
22:47 and you will have no control over it anymore.
22:50 Chili peppers contain a chemical called capsaicin, which is what makes them spicy.
22:55 It's the same stuff used in pepper spray.
22:59 You would have to eat quite a lot to risk your life,
23:02 but the results can nonetheless be extremely painful.
23:05 Safety gear for sports and work are there to keep you safe.
23:15 Even if you think they're an encumbrance, wear them.
23:18 They could have saved the lives of many, and they could save you.
23:22 Eating disorders have the highest mortality rate of any mental illness in the United States.
23:29 If you or someone you know are suffering, please seek help.
23:33 A belt has many more uses than keeping your pants up.
23:37 It can also be used in emergencies, like applying a tourniquet,
23:40 creating an arm sling, or even defending yourself.
23:44 It's important to remember different types of stressors before you make important decisions.
23:50 Remember this acronym, developed for people recovering from substance abuse issues.
23:54 HALT
23:55 Are you hungry?
23:57 Angry?
23:57 Lonely?
23:58 Tired?
23:59 You can understand why you might feel triggered or upset by checking in with yourself daily.
24:05 That way, you can avoid making poor decisions that will make things worse.
24:10 Allergies can develop later in life,
24:13 even with things you might have been in love with when you were younger.
24:16 This can be because of exposure to new allergens in the environment,
24:20 family history, and changes in the immune system.
24:23 So be careful, you might not be able to enjoy all that dairy, fish, or nuts without consequences.
24:30 Mascot outfits can trap heat incredibly well.
24:45 So performing rigorous activity for prolonged periods can quickly lead to heat exhaustion.
24:50 Take regular breaks, and stay hydrated if you ever find yourself in one.
24:55 When a microwave oven is turned on, the appliance begins producing
25:00 microwaves, which causes the item inside to vibrate until it's hot.
25:04 Metal is bad at absorbing microwaves, causing sparks to fly and even an explosion.
25:11 So keep metal out of the microwave, it happens more than you'd think.
25:16 If you find someone unconscious, putting them into the recovery position could save their life.
25:21 After you've checked that the area is safe and called emergency services,
25:25 place their arm closest to you at a right angle to their body,
25:29 with the elbow bent and palm facing up.
25:32 Put their other arm across their chest and the back of their hand against the cheek closest to you.
25:39 While holding their arm there, pull their furthest knee up until their foot is flat on the ground,
25:45 and roll them over onto their side, facing towards you.
25:49 Tilt their chin back to open their airway and check for blockages.
25:53 Electric devices don't just break in water, they can also send out electrical currents.
25:59 It takes very little water to be electrocuted, so please keep appliances and devices away from water.
26:06 Dialing emergency services might work even if your phone says you have no signal.
26:11 In the United States, networks must push through emergency service calls on any available network,
26:18 even private ones, so don't be afraid to call if you need it.
26:23 After you've had people over, make sure that windows and doors are locked properly
26:28 to prevent a possible intrusion, as some people forget to lock doors,
26:32 or tradesmen forget to remove tape from latches.
26:36 Even if you don't know how to swim, it can be relatively simple to float.
26:41 Relax, take some deep breaths, lie backwards and stretch your arms and legs out.
26:47 Keep your face out of the water and only make gentle movements.
26:51 Let yourself bob about, and now think about how you're going to get out of the water.
26:56 It's common for people to charge their phones in their bed, but the charger can give off heat,
27:02 and if that heat has nowhere to go, it might catch a flame.
27:06 Blue light from phones prevents you from sleeping anyway,
27:09 so charge it elsewhere, or maybe even in another room.
27:13 Speaking of electrical fires, overloaded extension cords are also dangerous.
27:19 This is because when too many devices are plugged in, the cord can overheat and catch fire.
27:32 Trains are bigger and wider than the tracks, so even just standing beside a track while a train
27:39 passes by could seriously injure you. Cars that catch fire can very quickly explode.
27:46 If you are in a car accident and a car is on fire, get out of the car as quickly as possible,
27:52 and move at least 100 feet away from the burning vehicle.
27:57 An old folk remedy for burns described covering them with oil, grease, or butter.
28:03 The idea was to seal the burn from air, preventing infections.
28:07 However, medical advice has advanced since then.
28:10 You should, instead, cool the burn with running water for 20 to 30 minutes.
28:16 Using these other substances can hold the heat in the skin, worsening the burn.
28:21 Wearing a seatbelt in a car can reduce the risk of death or serious injury by up to 50%.
28:27 Mosquitoes kill more people than any other animal, responsible for almost 1 million deaths a year
28:41 through the transmission of diseases such as malaria and dengue fever.
28:46 When traveling to high-risk areas, bring anti-malarial medication.
28:50 If you're bitten, watch out for symptoms, and if you do feel sick, seek medical attention.
28:55 The box jellyfish is considered the world's most venomous marine animal,
29:03 with enough venom in one tentacle to kill up to 60 humans.
29:08 There are artificial intelligences that can copy every part of your likeness,
29:13 from your style of speaking, physical appearance, and even your voice.
29:17 As such, everyone is even more at risk of falling prey to very convincing scams and fake news.
29:24 Do your research, be scrutinous, and maybe even have a keyword for your close friends or family
29:30 in case you get targeted by people using this technology maliciously.
29:35 Intergenerational trauma is when the effects of trauma transmit to the children of the
29:47 people who have suffered traumatic experiences.
29:50 It can benefit both you and your kids to seek help when it's needed,
29:54 and take care of your mental health.
29:56 Different countries have different laws.
30:00 Some enforce long prison sentences, and even the death penalty for crimes that are treated
30:05 more leniently in other places in the world.
30:08 Make sure to carefully research the laws in countries you're traveling to,
30:12 and avoid breaking any local laws.
30:15 Hair dryers, curling irons, and other heated styling tools can reach really high temperatures,
30:21 making them burn hazards if misused.
30:24 Despite common belief, Twinkies do not remain edible for decades.
30:30 They typically have a shelf life of around 45 days, and like most other food,
30:35 can lead to food poisoning if eaten after the recommended date.
30:40 There's a common misconception that tampons are an effective way to stop the bleeding
30:46 of a gunshot wound.
30:47 This is not the case.
30:49 Inserting a foreign object into the wound can cause further injury and bleeding.
30:54 Instead, apply pressure to the wound and call for emergency medical assistance.
30:59 Lightning can and often does strike twice in the same place.
31:05 During a thunderstorm, lightning tends to hit objects or locations that are more conductive
31:10 or prominent.
31:11 For example, the Empire State Building in New York is struck by lightning approximately
31:17 23 times yearly.
31:19 Antibiotics will not cure or even aid a cold.
31:24 These are prescribed to treat bacterial diseases and secondary infections,
31:29 and are generally ineffective against viruses.
31:33 Urine is not sterile, not even in the bladder.
31:38 So if you've ever heard that you should pee on a jellyfish sting or wounds to sterilize
31:43 it, don't.
31:45 Unlike in the movies, you should not attempt to suck venom from a snake bite or apply
31:57 a tourniquet.
31:57 Instead, move the victim out of harm's way, have them lie down with the wound below their
32:10 heart, and transport them to the nearest medical facility.
32:13 Also, if you get bitten by a wild mammal, you should get the rabies vaccine immediately,
32:19 as it is one of the most lethal diseases on the planet.
32:24 If you break a bone, follow these steps.
32:27 Call for help, attempt to stop any bleeding, and immobilize the injured area.
32:33 Your car thermometer is not 100% accurate.
32:37 Most cars are equipped with a thermistor behind the grille, which is exposed to heat radiating
32:44 from the roadway.
32:46 So even if your thermometer doesn't read below freezing, there could still be black
32:51 ice on the road.
32:52 Be aware of road conditions and give your thermometer a few degrees buffer and it could
32:58 save your life.
32:59 Blue lights steal your sleep time, disrupting the brain secretion of melatonin.
33:05 So before you go to bed, place that phone in another room.
33:09 Keeping your phone face down will save battery, which could become important in an emergency.
33:16 This will keep it from lighting up when it receives notifications.
33:20 Don't eat snow for hydration.
33:23 Since it takes so much energy for your body to melt the ice, you'll end up further dehydrated
33:29 than what you gain, plus lose essential body heat while you're at it.
33:34 You can start a fire with a 9-volt battery and steel wool.
33:39 If you rub the battery against the steel wool, it should begin to spark.
33:44 Place it beneath kindling and you'll have an emergency campfire.
33:48 Be sure to have water nearby if you need to extinguish it.
33:51 An overloaded key ring could damage your car's ignition mechanism.
33:56 All the weight can wear out sensitive internal components, making it so your car won't
34:02 be able to start.
34:03 Laughter is proven to improve blood flow, immune response, blood sugar levels, and
34:14 relaxation.
34:16 So watching some funny internet clips could actually be helping your health.
34:19 If you ever get stuck in a rip current, don't panic and try to swim directly back to the
34:27 shore.
34:27 Instead, swim across the current, parallel to the shore, until you're out of the rip.
34:33 Speaking of which, if you need to catch your breath while exiting a rip, relax and float
34:40 for around a minute or so.
34:42 Some rip currents recirculate and might pull you closer to shore rather than just further
34:47 away.
34:48 If you think you're having a heart attack, you should chew aspirin, not swallow.
34:55 This works faster to inhibit platelets, which trigger blood clotting.
35:00 If you come across a mountain lion, don't run away.
35:04 Calmly back away, maintaining eye contact without bending over or crouching.
35:10 If it starts moving towards you, throw things at it.
35:13 And if it starts getting aggressive, act as big and intimidating as possible.
35:18 Never, ever go underneath a pin setter at a bowling alley, which includes sliding into
35:25 the pins as a joke.
35:26 The force is so strong on some of these machines that it can cause serious or even fatal
35:32 injuries.
35:34 They're good machines, but just like any running machinery, they're dangerous.
35:38 You've got gears, you've got pulleys, everything's running.
35:42 If you're at a beach on vacation and the water suddenly recedes from the coastline,
35:47 run for high ground.
35:49 A tsunami is on its way.
35:51 Other signs include severe ground shaking and a roaring sound, as if from a train or
35:58 plane.
35:59 If a tornado doesn't look like it's moving left or right, it might be moving right towards
36:06 you.
36:06 Get to safety!
36:07 If someone has been stabbed or punctured by a sharp object, leave the object in the
36:14 body.
36:14 It will potentially prevent blood loss.
36:17 Apply direct pressure either side of the object.
36:20 You should also sit or lie the person down and elevate their legs if they're in shock.
36:27 If the object isn't still inside the victim, apply direct pressure to the wound to stop
36:32 the bleeding.
36:33 It takes 10 minutes for clots to form.
36:36 Use gloves, clean cloth, or plastic bags to protect yourself from blood contamination.
36:42 If a room in the house has a fishy scent, check your electrical outlets and start unplugging
36:49 appliances.
36:50 That smell could indicate overheating electrical components.
36:54 You might just save yourself from an electric fire.
36:57 The "bystander effect" is when people are less likely to help a victim when there are
37:03 other people standing around.
37:05 So, when crying out for help, pick out an individual in the crowd, make eye contact,
37:11 and call on that person for help.
37:13 Most drunk driving deaths occur between midnight and 3am in the United States.
37:20 Maybe avoid the roads during these times if you can help it.
37:25 If you see a bear, you should stand tall, talk calmly, and back away without making
37:32 eye contact.
37:33 In the rare case that you're attacked, you may have heard this rhyme.
37:37 If it's brown, lay down.
37:39 If it's black, fight back.
37:41 If it's white, good night.
37:44 If a brown bear attacks, you should play dead, or you'll make the attack worse.
37:49 As for a black bear, which is smaller, you should fight back.
37:53 A polar bear may see you as prey, so you should definitely fight back.
37:59 But the odds are not good.
38:02 If you're out and your drink tastes unusually salty, do not continue drinking it.
38:08 GHB has a salty taste, although it's easily masked by other flavors.
38:14 Your best bet is to never leave your drink unattended.
38:18 If you ever wake up in the middle of the night to the smell of gas, do not turn on the light.
38:25 A spark from a light switch could ignite the gas.
38:29 If you ever see square waves in the ocean, get out.
38:33 They can create powerful currents and rifts.
38:37 If one of your pupils reflects white in a picture, it could be just a reflection, but
38:43 it could also be a sign that something is wrong with your eye, such as a cataract or
38:49 even cancer.
38:50 Normalcy bias is when people underestimate the threat of danger despite warning signs.
38:57 About 70% of people display this bias in disasters, delaying evacuation.
39:02 If you're asked to leave the area due to impending danger, just get out of there.
39:08 You can use condoms as makeshift water storage, as they're incredibly elastic.
39:14 Just make sure they're lubeless, though.
39:17 Tie the end around a stick so you can easily untie it.
39:20 You can also wrap it in a sock to prevent it being pierced.
39:23 If you're caught in a thunderstorm, do not stand near a tree.
39:36 It's a natural lightning rod.
39:38 If the air tingles and your hair stands on end, lightning is about to strike nearby.
39:43 Crouch, tuck your head, and put your hands over your ears.
39:47 Don't lie flat, as wet ground conducts electricity.
39:52 If a power line falls next to you, don't walk or run.
39:56 Shuffle or bunnyhop to safety.
39:59 Seems silly, but it makes sure that the voltage to each foot is the same, so that
40:04 electricity doesn't run up one leg and down the other.
40:07 When calling an emergency number, like 911, be prepared to give them an address or location
40:14 first, so even if you're cut off, they know where you are.
40:18 Follow up with the nature of your emergency.
40:21 Encounter an emergency while abroad?
40:24 The number 112 can be used in most European countries, forwarding you to local emergency
40:31 numbers.
40:32 It also works in some African and Asian countries, as well as North America.
40:37 Hold your nose when you jump into rivers and lakes, especially if the water is stagnant.
40:43 This protects against infiltration by dangerous amoeba.
40:47 Also, if you're falling into water from a height, enter feet first with your arms at
40:53 your sides.
40:54 This can protect you from major injuries.
40:57 If you ever feel like someone is following your car, take 4 right turns and it will make
41:02 a circle.
41:03 If they are still behind you, that means they are following you.
41:07 If that's the case, go somewhere where people are, even a police station if you need to.
41:12 If you accidentally disturb a beehive or wasp nest, do NOT run for the water.
41:19 They'll just wait for you to resurface.
41:21 Run fast and as far as you can, because eventually, they will stop following you.
41:27 Swatting at them will only make things worse, and if you get stung, pull the stinger out
41:32 as soon as possible.
41:33 The more colorful and vivid the animal is, the more likely it's poisonous.
41:45 If you ever find yourself in a falling elevator, do NOT try to jump at the last second to avoid
41:52 impact or bend your knees to absorb the impact.
41:55 Instead, lying flat on your back and covering your face is your best bet for survival.
42:01 If you find yourself lost in the wilderness and can't retrace your steps, walk downhill.
42:08 You're more likely to hit a trail, road, or buildings.
42:12 You're also likely to find a water source, which people often build around.
42:16 And if you find a fence, follow it.
42:19 If your plane has to make an emergency water landing, do NOT inflate your life jacket on
42:25 the inside of the aircraft.
42:27 It will make it harder for you to move to the emergency exits, especially if water rushes
42:33 in.
42:33 Instead, swim to the exit and then inflate your jacket.
42:38 Heat travels through liquid faster than gas.
42:42 So, if you want to stay warm, keep yourself and your clothes dry, so that heat transfers
42:48 from your body more slowly.
42:50 You can miss something in plain sight due to inattentional blindness, which can occur
42:56 when your brain is attending to too many stimuli.
43:00 One example is when you're walking and on your phone at the same time.
43:03 This leaves you open to walking into objects or into traffic.
43:08 If you feel sick and don't want to throw up, hum.
43:12 Humming suppresses the gag reflex.
43:15 The limits of the human body tend to follow rules of three.
43:23 People can generally go three minutes without air, three hours without shelter in extreme
43:28 weather conditions, three days without water, and three weeks without food.
43:33 The most common sign of a heart attack is pain or discomfort in your chest, especially
43:39 a feeling of pressure or squeezing.
43:42 It can sometimes spread out to other areas and be accompanied by fatigue, a cold sweat,
43:48 lightheadedness, nausea, or shortness of breath.
43:51 If this happens, seek urgent medical attention.
43:54 Women can experience heart attacks differently to men.
43:59 While chest pain is common in both men and women, women are more likely to feel sick,
44:04 experience shortness of breath, or have back, neck, or jaw pain.
44:09 The bottom line is there's more variation in heart attack symptoms in women,
44:13 and women tend to wait to get them investigated.
44:15 If your stool has black specks in it, which some describe as looking like coffee grounds,
44:22 seek medical attention.
44:24 It might mean you have gastrointestinal bleeding.
44:28 When walking down stairs, don't put your hands in your pockets.
44:32 If you happen to slip and fall, your arms won't be able to grab a railing or break your fall.
44:38 You don't have to pay money on any type of phone to call 911, so don't bother hunting
44:51 for change if you're using a payphone.
44:53 Most fire deaths are caused by smoke inhalation.
44:57 Not burns.
44:59 If you find yourself caught in one, stay low to the ground and get out of there ASAP.
45:04 Never put your feet on a car dashboard.
45:08 Airbags deploy at hundreds of miles per hour and can break your nose when seated normally.
45:14 But a broken nose is better than broken legs.
45:18 Don't use bleach and cleaning products that contain ammonia at the same time in the same room.
45:26 Their vapors will mix in the air and create chloramine, which can damage your respiratory
45:32 tract.
45:32 If your vehicle gets stuck on a railroad, get off the tracks immediately and run away
45:48 at a 45-degree angle in the direction the train is coming from.
45:53 This protects you from being in the splash zone of debris if your vehicle gets hit.
45:58 Also, look for a sign with an emergency number for the railroad or call 911, and they can
46:05 inform any approaching trains.
46:07 A wagging tail does not always mean a dog is friendly or happy.
46:14 Dogs can also wag their tail when fearful or as a warning.
46:19 Always ask the owner before you pet their dog.
46:22 Both the words flammable and inflammable mean that the product is capable of being
46:29 easily ignited and of burning quickly.
46:32 Non-flammable means not easily ignited.
46:36 Chemical burns are different from heat and fire burns.
46:39 You might not feel pain right away, but they can cause irreparable damage to your skin.
46:45 If you get chemicals on you, be sure to read the labels and use the recommended method,
46:51 as water can often not be enough.
46:53 Purple flags on the beach indicate dangerous sea life in the area.
47:06 Red flags warn of serious hazards, such as high surf or dangerous currents.
47:11 A double red flag means the water is closed to swimming.
47:15 Use the acronym FAST to identify symptoms of a stroke.
47:20 F stands for face drooping.
47:22 Does one side of the person's face droop?
47:25 For example, in a crooked smile.
47:27 A is for arm weakness.
47:29 Can they raise both arms?
47:31 S is for speech difficulties.
47:33 Are they slurring?
47:35 T stands for time.
47:37 If you see any of these signs, it's time to call emergency services.
47:42 Many species of mushrooms are poisonous to humans and can even be fatal.
47:48 So do not eat wild mushrooms.
47:51 Dangerous ones can also look convincingly like edible ones.
47:55 After you fall into very cold water, dry yourself off, dress in layers, and warm up gradually.
48:04 A phenomenon known as afterdrop means that if you warm up rapidly,
48:09 your core temperature may initially continue to cool.
48:13 If a stranger tries to force you into their car, shout for help and fight back as hard as you can.
48:20 Escape will be more difficult once you're taken to a new location.
48:24 A knife can be lethal, even in inexperienced hands.
48:29 If someone pulls one on you, don't escalate the situation.
48:33 Run away if you can.
48:34 If you can't, hand them what they want.
48:37 Your wallet isn't worth your life.
48:40 "That's not a knife.
48:41 That's a knife."
48:45 Telling people where you're going increases your chance of survival if you get lost,
48:51 injured, or kidnapped.
48:53 In 2021, unintentional shooting deaths accounted for over 4% of gun-related deaths in the US.
49:00 Many involved children.
49:02 In the home, firearms should be stored unloaded and in a secure place behind child-proof safety
49:08 locks. Using water to put out a grease or oil fire will make the fire worse.
49:15 Instead, turn off the stove to cut off the heat and cover the pot to cut off oxygen.
49:20 "Oh my God!"
49:22 "Get out of the way!"
49:24 You can use your pants as a life preserver by taking them off,
49:28 tying the legs together, and filling your pants with air, either by scooping the
49:32 waist down through the air into the water or by breathing into the waist from below.
49:38 Scrunch the waist tight to prevent air escaping.
49:41 About half of the passengers killed in car accidents in 2020 in the US were not wearing
49:48 seatbelts. Buckle up.
49:50 Many backpacks have a built-in whistle to get attention.
49:54 Especially in windy weather, don't camp under a tree.
49:59 Tree limbs sometimes shed or break off, and could come down on your tent.
50:05 If you fall into quicksand, don't panic.
50:08 You can only really sink up to your waist, wriggle your legs to loosen them,
50:13 sit back, and try to float out.
50:16 It's okay to ask for help if you're feeling depressed.
50:19 There are plenty of publicly available numbers to call if you need someone to talk to.
50:25 If you hit your head and briefly lose consciousness, seek medical care when you wake up.
50:31 You likely have a concussion.
50:33 You could also have an epidural hematoma, bleeding between your skull and the membrane
50:39 around your brain.
50:40 Toilets are more deadly than sharks.
50:43 Each year in the US, around 40,000 people are injured in toilet seat-related accidents.
50:49 Make sure not to slip on a wet bathroom floor.
50:53 Distracted driving is the leading cause of car accidents in the US,
50:58 so stay off your phone while driving.
51:01 A gun trigger can be pulled faster than you can react,
51:05 so don't try to disarm someone if you're being robbed.
51:08 Things are replaceable.
51:09 Your life is not.
51:11 You can estimate the remaining daylight time by extending your arm in front of you
51:16 and holding your hand out with your pinky finger on the horizon line.
51:21 The width of one finger is roughly equal to the distance the sun will travel in 15 minutes.
51:27 Four fingers equals one hour.
51:29 If you're buried in an avalanche and disorientated, spit.
51:34 Your saliva will follow the gravity, and you can dig in the opposite direction.
51:39 Smoking causes cancer.
51:42 We know you know, but it's an important one.
51:44 The harder you make it for a burglar to enter, the less likely a break-in will occur.
51:51 So always lock your doors.
51:53 Also, be careful when someone comes to the door.
51:57 Just because the doorbell rings doesn't mean you're obligated to open the door.
52:01 Horses cannot see immediately in front of or behind them,
52:10 and horse kicks are incredibly powerful, so never approach a horse from behind.
52:16 Stand on the side of the horse between the head and shoulder.
52:20 You can perform the Heimlich maneuver on yourself.
52:23 Form a fist just above the navel.
52:25 Place your other palm over the fist to push more firmly.
52:29 Drive your fist in and up in the diaphragm area, the top of your stomach,
52:34 and repeat until the object stuck in your throat dislodges.
52:38 If a man takes a pregnancy test and the result is positive,
52:44 it might be the sign of testicular cancer.
52:47 Testicular cancer can hit men at any age, but almost half of the cases are found in men between 20 and 34.
52:53 The safest place to sit on a plane in the case of a plane crash is near the back in a middle seat.
53:00 The worst seats are on either side of the aisle in the middle of the aircraft,
53:04 which is almost double the fatality rate.
53:08 If you're stuck in a stampede, the most important thing is to stay on your feet.
53:14 Keep your hands around chest height to protect yourself and prevent being crushed.
53:19 If someone is drowning, remember this rhyme, "Reach or throw, don't go."
53:25 Use a long item to reach out for the victim to grab onto.
53:30 Otherwise, throw them something that floats.
53:33 If you approach without a flotation device,
53:36 a drowning person is likely to grab onto you and pull you under.
53:42 Even when someone has been pulled ashore after drowning,
53:45 that person can still die due to leftover water in their lungs.
53:50 This is called dry drowning.
53:53 Even if you've been saved from drowning, you still need urgent medical attention.
53:58 If you need to break a car window, aim for the edges or corners.
54:03 The center of the window is usually the strongest part.
54:07 "Push it in the corner and apply pressure, and there we have it."
54:13 Embassies and consulates have emergency numbers they answer 24 hours a day.
54:18 When abroad, it can pay to have this number saved in your phone.
54:23 If you possess a gun, you're more likely to be shot during an assault.
54:29 This is especially true in cases where the victim has a chance to resist.
54:35 "Hey old man, give me everything."
54:37 "Oh, oh, call an ambulance, call an ambulance!"
54:43 "But not for me!"
54:44 Some thieves use posts on social media to identify and plan robberies.
54:51 When you check in somewhere, it indicates you're not at home.
54:55 "How easy would it be to find the location of her house?"
54:57 "Well, for my car, I'd reach and get the location of her house.
55:00 At the same time, I'd go into the life thing.
55:03 Sometimes there are chests in there."
55:05 Although it's rare, alcohol withdrawal can be fatal.
55:09 If you have a long-standing problem with alcohol and show signs of withdrawal,
55:14 like tremors, insomnia, nausea, or anxiety, get medical assistance.
55:19 People do not outgrow asthma.
55:23 Whilst some might become asymptomatic as they get older, the potential for asthma remains.
55:30 Always carry an inhaler and keep the prescription up to date,
55:33 even if you haven't had symptoms for years.
55:37 You do not have to wait 24 hours to report a missing person.
55:42 There is no time limit, and the sooner you report it, the better.
55:45 One of the symptoms of hypothermia is drowsiness.
55:50 If you or someone else has stopped shaking from extreme cold and is feeling sleepy,
55:56 it's not a good sign.
55:58 Get inside and warm up.
56:01 Closed doors can slow the spread of fire and smoke.
56:05 With this in mind, it's best to sleep with the door of your bedroom shut.
56:09 Also, be sure to check the batteries in your smoke alarms regularly.
56:13 While driving, if the accelerator pedal gets stuck or something else causes
56:21 unintended acceleration in your car, press the brakes firmly and put it in neutral.
56:27 Extinguishing a fire is a lot easier with a fire extinguisher, so buy one before you need one.
56:33 The best preventions for heart disease, which is the leading cause of death in the US,
56:39 are eating a healthy diet, exercising regularly, maintaining a healthy weight,
56:45 limiting your alcohol intake, not smoking,
56:49 getting your blood pressure checked regularly, and managing diabetes if you have it.
56:54 Keeping healthy and not smoking can also reduce your chance of getting cancer,
56:59 the second leading cause of death in the US.
57:02 But you should also talk to your doctor about how to do self-checks
57:06 and how often you should get screened.
57:08 Your subconscious mind will be able to pick up warning signs that your conscious mind might not,
57:15 so if a situation doesn't add up and something feels off, trust your gut and instincts.
