When I see pictures of people and pools, I rarely see anyone swimming. They are jumping or splashing, or just standing there. They seem to be enjoying themselves, but the only place I see actual swimming is at a pool in the Y.
The same with the beach/ocean. People float or jump waves, but there's not much serious swimming. I like to swim -- really swim. I like to get way out there and let go. Just the water, the sharks and jelly fish and me.
