I worked with a guy who was a Ninjutsu instructor and I soon started off as a private student. He showed me how effective the Dim mak points really are when I trained with him. I must say they have come in very handy in self defence at several occasions over the years. I have held down an attacker that was way bigger and stronger than me with two fingers and holding him to the ground he soon gave up the fight, apologised and ran off.
