I've always wanted to go scuba diving. When I was a kid I used to pretend I had scuba gear and stay under as long as possible.
I love the ocean, I've never been scuba diving though.
If I were to do it, I'd want to do is safely. You can get seriously messed up by surfacing too fast. The apparatus can expand the gases in your blood.
For sure, you can use the Wim Hoff breathing method to hold your breath even longer which means more time getting to see stuff too!
I've heard of that. Yeah, it'd be terrible to experience symptoms of decompression for up to days.
Yeah I've heard of people getting the bends so bad it kills them.
I saw something on television once about an incident when someone ascended too fast. They put them in a pressure chamber but it got released by accident...sucked his body through a small hole.
