Yes and some people use it to paint the fence and some to wax their car. You are supposed to be warriors studying the art of war. War is not a pretty thing. Art does not have to be pretty. Killing is never honourable. Keep it real and what it was intended for. Learn to fight well, Karate teaches this. Dont get lost in the political correct crap of how it makes you better people. It might do that but thats not what its about. Fighting is a lonely place. Lets face it if you only wnted to get fit you would run or something. Truth is humans are destructive and highly defensive. You would have been warriors in another time.
