Guy Dives In Frozen Lake And Struggles To Come Back Up

This guy stood on top of a frozen lake. He held his breath and dived in through a hole in the ice sheet. He swam a short distance towards another opening in the ice, but could not find it. He swam back to where he had jumped in, and after struggling for a bit, he found the hole and came back up through it. He was breathless and freezing when he surfaced.
