I’ve always been a bit of a water baby and love swimming. I don’t do laps anywhere near often enough but love going for a swim at the beach, night time skinnydips etc. It’s an unusual concept to me, as much as I love swimming, that you can feel so free in the water and glide beautifully weightlessly yet being a human in water, you can’t be totally free. There is kinda a relatively critical need for oxygen. Until we evolve gills, which isn’t looking likely, we are just going to have to keep coming up for air.
