I've never experienced dim mak myself , but check out the Dim Mak video here, with master Duan Bao Hua. http://www.taoofdefiance.com/category/martial-arts/traditional-martial-arts/kung-fu/ you'll need to click "click to read more" in the "mind, body and kick.." article, because your ridiculuous automated censor won't let me post that URL because it has the word a-s-s in it. Its the name of a TV program, for F's sake. As in "Mind, body and kick a-s-s moves". anyway, seems pretty real to me.. this tai chi master, Erle Montaigue also claims true tai chi uses pressure point strikes and has released a tonne of videos books and articles about it http://taichiworld.com/ Don't know how legit he is though.
