Re: Self defense against what???
Statistics (if reported correctly... </understatement>) are a valuable source to dispel most of the myths and rubbish I hear from the plebe. For example, most rapes (more than 55%) are committed by someone known to the victim, mostly their "boyfriend" (30%+). Scary.
BTW, I believe that some Japanese universities do have degrees in martial arts. I would be surprise if China/Thailand/Korea didn't have the same. But I don't know for sure. Anyone care to enlighten me?
