[QUOTE=drgoodtrips;919727]I was a green belt in karate (Shotokan) when I was younger. I did it for about five or six years before high school got to be too demanding for me to keep it up. I didn't have enough time to practice and continue to advance. Once I finish my master's degree, I think I might take it up again though - it was a good way to stay in shape.[/QUOTE]

Man, you said it. I don't think I've ever been in better shape than when I was doing Martial Arts (though I still exercise regularly). It's a heart workout like almost no other. Maybe once I finish school in the next few years I'll get back into it as well.
