I Love Swimming

True!

We are made mostly of water, so our bodies rejoice in being immersed in it on the outside too...

Skinny dipping?

Yes, totally

My dad did a hundred laps twice a week from his forties till he died.
Probably a great way to meditate and be completely private

That and running... nothing quite like a little simple, low-brainpower exercise.

Been along time since I did that

I agree
