I hate snorkeling since I always seem like I'm going to drown. Give me a tank of air and I'm good to go. I love the peace and quiet of diving. You only hear your breath. To me it's so relaxing. I could see nothing on a dive and be happy. Now if I see some turtles, fish, sharks, I'll be talking about it for days.
I don't dive as much but when I do it's my happy place.
