The
wonderful thing about swimming, is that for anyone who ever did it
competitively, no matter how long ago it was, you will always generally feel
athletically
superior to most everyone else in a public pool. Swimming involves a
technique that is far, far more important to doing it well, than most other forms of
exercise. The technique goes a lot farther than
strength, or even
endurance.
It's always nice to feel like you're good at something.
