response 1 :-
Every few months I check back with this posting to see if people are still falling for this nonsense.Apparently the answer is yes.If this were possible every soldier, police officer and Ultimate Fighter would be using it.They don't because this is nonsense.Use common sense.There is no magic "touch" only hard training and practice and real study on pressure points.This guy falls to the floor like he got tazzered.Pressure points don't work like that.

the other response of note:-
You can see the same thing at any Pentecostal Sunday Service. It's called "slain in the spirit", no martial arts.
