I have had quite a few interesting experiences that lead me to guess that most of us will ever really only know some very low level stuff. I have had my heart stopped dead in my chest, pounded into and held down on the ground by someone standing several feet away, seen someone get their mind scrambled almost to the point they were salivating, have experienced the real one inch punch, more like one inch touch (it lifted me straight up off the ground and threw me back 10 feet in mid air.) These are merely experiences which open students up to higher level possibilities. Wish I could do them, though...
Ah well, I guess I've just been around Asian arts too long, Shaun. What you're describing, except for the punch, says more about you than anything else. That's why those demo's are referred to by so many Chinese as "psychological power". We used to ask people to try these things on us. But if this is where the conversation is going, I'm bailing. Arriola's your man.
