I'm currently studying Karate (Shotokan style). I've been with it for about 3 years, and dig it a lot.
I tried Northern Kung Fu for not quite a year, and the postures and everything just *totaled* me.
Back in college, I took Kendo for a very cool year.
In high school, I was a wrestler, and a pretty good one at that. Also took 3 years of Judo, which worked out pretty well.
You'd think that with a solid 11+ years in various martial arts, I could throw Ki blasts, but unfortunately, since I switched around so much, I can barely levitate.
