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.
