00:00Do you notice anything on these hands?
00:06That's right, they're all left-handed.
00:08Do you know anyone who's left-handed or left-handed?
00:11Or maybe you're left-handed yourself?
00:13Get ready, because you're about to be amazed!
00:20Lefty, Southpaw, left-handed.
00:23These people are the dominant hand,
00:25or what's commonly used in everyday activities,
00:28is the left hand.
00:29Approximately 10% down of the world population,
00:32or 1 out of 10 people, are left-handed.
00:35That's why they say,
00:36we're living in a right-handed world.
00:38In fact, some everyday things
00:40are usually done for the right-handers.
00:43Unfair, lefty friends?
00:54Scissors.
00:58Bread knife.
01:00That's why lefties say the struggle is real.
01:05Based on life experience,
01:06Dexter, EJ, and Kyle agreed.
01:10Maybe the biggest struggle as a left-handed person
01:14is writing.
01:17Especially on notebooks.
01:19Usually, what we write is smudged on our hands.
01:24When you're eating, and you're all close together,
01:27and our mouth is in line with the person eating on the right,
01:35that's the difficult struggle.
01:37When you're using scissors,
01:39because it's really designed for the right-handed,
01:43so if you use it on the left, you'll have a hard time.
01:47Are you lefty?
01:48Are you lefty?
01:49Are you lefty?
01:50Are you lefty?
01:51Are you lefty?
01:52Are you lefty?
01:55People believe that being lefty, or left-handed,
01:59has something to do with the brain.
02:02Now, from a 2017 recent study,
02:04apparently, it's not.
02:06But it comes from the spinal cord.
02:10Wow!
02:13It all starts while the baby is breastfeeding.
02:15There's a gene activity in the mother's spinal cord.
02:18Because of this gene activity,
02:20the fetus can already start moving.
02:22It chooses a favorite hand
02:24before the fetus's brain can control it.
02:28It's said that genetic influence,
02:31or being lefty, depends on the parent.
02:34Two right-handed parents have a 9% chance
02:39that their child will be lefty.
02:42Meanwhile, if one of the parents is lefty,
02:45chances will be raised to 19%.
02:49And if both parents are lefty,
02:52there's a 26% chance
02:55that their child will also be lefty.
02:58If you're lefty,
03:00you're just like Aristotle and Michelangelo,
03:03as well as the celebrities Oprah,
03:05Justin Bieber, Angelina Jolie,
03:07and the billionaire Bill Gates.
03:09In the Philippines,
03:10there are also many lefty celebrities,
03:12like Pam Bansang Bay, Alden Richards,
03:14Jenelyn Mercado, and Dennis Trillo.
03:16Even cartoon characters are lefty.
03:19Bart Simpson, Garfield, and Chucky Sirogratz
03:22are also left-handers.
03:24Did you know there's a day to celebrate your left-handedness?
03:28That's right!
03:29August 13 is International Left-Handers Day!
03:36But our neighbor, Julius Landico,
03:38is a dead man when it comes to being left-handed or right-handed.
03:46Because he says he can use both hands
03:48in his daily activities.
03:56In his case,
03:57he's one of the 1% of the population
04:00that can use the left and the right hand
04:03as both dominant hands.
04:05And this is called ambidextrous.
04:36Studies have shown
04:38that there's no reason
04:41why a person becomes ambidextrous.
04:45Sometimes, a person becomes ambidextrous
04:48because their parents force them.
04:52Sometimes, a child is left-handed
04:55and the mother gets angry
04:57because she has to use her right hand.
05:00So now, she's practicing.
05:02Sometimes, in reality,
05:04there are people who are not ambidextrous
05:07because they practice
05:09and they always use their hands.
05:11This is what makes them dominant.
