Any nerdfighters who do martial arts out there? If so: What sort? How long have you been training? What belt are you? (If your branch uses belts, that is) Why did you start, and why do you still train? Aaaand...anything else you might like to add.
I train ju jitsu, and I've been training for ...some years. I really don't know any more. I'm a black belt, 1st dan. I started training just because all of my friends did, and I didn't want to be left out. Not one of the friends I started with still train, though...oh well.
