Re: Martial arts (could use your thoughts)
If at all available in the are I suggest Wing Tsun Kung Fu (or Wing Chun). It uses very interesting soft techniques that force the opponents strenght against him. It doesnt require too much fitness level and can be a very effective self defence means.
About 4 years ago I had stopped drumming completely in pursuit of this martial arts and I made a whole year learning almost full time. The techniques are deep and effective and most of my flow in drums I developed from there.
I had practiced boxing too for a while, even wrestling for 3 years , karate and Ninjustu for about a year. I stopped boxing cos of the too much strikes to the head. But from my experience I suggest Wing Chun Kung fu.
