I have to be the grinch here, MA is what it is for different people. Some people take drugs and train, some people train to learn how to kill, some people train to get fit. MA for you prevented you from taking drugs, but MA only enhances what character you already have. I know people who take beta blockers before comps, they learn the same art from the same sensei and where taught the same dicipline I was, I dont now, nor ever will take drugs! Just something to think about!
