Sometimes they don't even manage to make splashes and it looks like they're just stationary when in fact they're an impending sinking stone in under 30s.

I was once called out by a lifeguard about that, as I was just chilling there enjoying my own stillness in a moment of zen; the lifeguard essentially pointed out that for them it was a false positive they had to weed out, and if I wanted to be helpful I could still enjoy zenness but assume a slightly different position that made it a bit more obvious I was not a case of drowning.

As teenagers, we had a diving competition. Stay underwater for as long as possible.

Of course we saved energy by being perfectly still and 'floating' beneath the pool's metal entrance stair case — as opposed to wasting energy pushing our bodies downwards.

Let's just say the lifeguard didn't like this method.

My siblings and I were avid swimmers and enjoyed diving to the bottoms of lakes and swimming around. The deepest I ever dove unassisted was 47 feet (in the ocean). Starting when I was 8 or so, we'd practice holding our breath in the bathtub as we floated face down and motionless. My record was about 2.5 minutes. I think my brother made it to 3.5 minutes. It must have been terrifying to my mom. She was clearly keeping a close eye on us, as she'd periodically tap us on our shoulders when we'd been under for an appreciable amount of time and we'd gently wave at her with our hand to let her know we were alright.

I'm going to be a parent in a few months. I hope my kid takes to the water like I did, but would prefer their interests in water activities aren't quite as nerve wracking.
