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.
