Well if he had studied directly under Xioa Wang he know by now that his beliefs in Qi and of primary importance and he would of let him know it as he did once when I met him. The literauture he has produced in articles over the years will testify to where he stands and I do not feel he would bother that much with a student who was so obviously against the idea and practice of Qi in a martial situation.
By the way Acpuncture does not work on the release of endorphins scenario. That idea was booted out years ago. Needles are certainly NOT inserted into nerves as it blimmimg well hurts to do such a thing, as anyone who has accidentally hand that done to them will testify for. Hitting nerves does nothing but make people go "OOOOWWWWWWWWW!!!!!", and holds no truck with chinese medicine.
