I think that on the whole you will only need to defend yourself if you get in trouble, and generally you only get in trouble if you go looking for trouble. It was mentioned earlier that martial arts saved a members life half a dozen times, to defend themselves from a mass bashing. Now I have no martial arts skills, nor have I ever had the need, or been in the situation to defend myself from a mass bashing.. What's right with this picture.?
Contempt breeds Contempt.
