If I was fitter, I would rather like to do Tae Kwon Do, it's the only martial art I have respect for. I used to do boxing, and found it to be much harder, and much more effective in combat, than karate and about half a dozen other types of martial art whom i've gotten into fights with. I sat in at a training session of Tae Kwon Do and firstly, got whuped when the teacher asked for a volunteer, and secondly, couldn't keep up with the training.
