I have 4 young kids and really appreciate this video. My wife and I have tried to teach each of them to swim at an early age because drowning is SO SILENT! Once we were at a local park lake with my daughter who really young. She was in like 1-2 feet of water, and we were both within 5 feet of her watching as intently as possible. Suddenly a little girl playing next to her said something like "are you ok?" which made us look and see our daughter's face was underwater and she was drowning. The whole thing lasted like 10 seconds, but it was still really scary. I think we would have seen in time regardless, but the fact that we were trying to watch so closely and almost missed it was crazy.
You also have to be very careful when multiple kids are in the pool. Sometimes a kid who is a great swimmer can drown when another kid starts panicking and climbs on top of them to stay afloat.
Another thing I've always wondered, why does it seem that all animals innately know how to swim, even young ones?
Maybe it is just that most have 4 legs and that helps, but I'd guess monkeys know how to swim too. Not sure. I mean even snakes know how to swim haha.
What makes people so bad at swimming? Our big heads?
This is a common beach sand [0]. It illustrates something absurd, I can't quite put my finger on what, about the relation between human society and technology. No one knows anything about the physical or chemical properties of sand on the beach. No one asks; no one cares. There are no EPA surveys of beach radioactivity. No beach signs warning beachgoers "do not eat the sand", or, "this beach is known to the state of California to cause cancer". But you take one handful of the beach into a plastic box, and accidentally walk it past the wrong regulatory compliance officer, and suddenly the US Army is burying your one-handful-of-beach-sand in a 55-gallon drum packed in bentonite.
It's one lens for nature, and one lens for the anthropogenic.
