I'm kinda the opposite about deep water. I don't like to float around on the surface if the water is deep, since I can't see far down, but I'd absolutely love to go scuba diving or something. I'd probably be scared doing it, but I think I'd love it anyway.

Pools are okay but I prefer swimming in lakes or the ocean. Feels fresher. I grew up swimming in the ocean every summer (rocky shores > sandy beaches!), so that's my favourite.
