Well, it turns out a lot of people do a lot of weird martial arts, most of which I've never heard of.
I do Yoshinkan Aikido (
http://www.aikido.org.il/). I've been doing it for a couple of years I guess but too a few years off in the middle (school). I love the motion and the relaxed state you get to in doing Jiu Waza techniques (flow motion). It's really amazing what you can do to a man without using almost no force at all, simply by redirecting the motion of the opponent.
