Good point, Ol '55!
I had a friend/classmate who played water polo. Its a very grueling sport that demands a high level of strength, stamina and conditioning. I was exposed to it in PE class at Navy and it kicked my butt. Two people you don't pick a fight with -- rugby players and water polo players!
One of my senior year roommates was a gymnast. He could do the "Iron Cross" all day long. Come to think of it, I wouldn't pick a fight with him, either...
I started out on the rowing team and switched to off-shore sailing (racing).
