Yas. Only thing I've been able to practice in any real way. I've switched disciplines often though, so haven't got very far in any of them. I got a belt grade from like 7 pretty different japanese, thai and korean styles, but my highest grade is judo 3. kyu from like 1996.

I did, as an exercise. Work kept me from sticking with it. I deeply regret not staying with it for physical fitness. Bummer too, my instructor became 9th Dan.
