I know of a Dim-Mak Instructor I had back in Jersey. He once told me how to incompasitate a man with a two finger strike on the side of the body. I diddnt believe it, told him he would have to hit me pretty hard. Like he pressed a key on a keyboard he hit me and I cried like a bitch on the ground. I never doubted him again. I believed him when he said that even though that is the least damaging thing he could do to someone, never beleive anyone who says they can kill you with a two finger strike.
As a matter of fact, "...just punch that fucker in the face, if he pulls a gun, run like hell. If he drops to the ground like you just did, kick him a few time then run. Cops are pretty quick these days."
I then proceeded to puke. I will never forget this day back in 2000.
