"'chi', as it is used for healing practices, is now finding correlatives in Western medicine."
It is not because Chi does not exist and cannot be demonstrated.
"'chi' is just a term used to explain the why of how this stuff works."
It explains nothing. It is a vague, malleable, nonsense term and an incorrect explanation of physical effects for the same reason, that it does not exist. There are no such energy fields as chi proponents insist. If there were, they would have been identified like any other form of energy.
"If I took a random person off the street and sat them in a chair in a University lecture hall where a graduate level seminar in chemistry was occuring, I dare say they would find that fairly 'mysterious'."
The difference is that ultimately there is a scientific explanation for chemical processes, unlike chi, which is a fantasy concept.
"I await you scientific explanation as to what exactly occurs when the needles are poked into someones skin, and how the endorphins are acted upon by that."
Not being a doctor, I am not in a position to do this in detail. To ask me for this again misses the point-it has been identified again and again as a testable, physical reaction (unlike chi ever). In any event the doctors I have spoken to seem to have a logical and scientifically proveable basis for their understanding of the process of releasing endorphins, amongst many other things. Unlike chi which is unproved and unproveable, sorry to be boring but because it does not exist.
Because you believe in something which does not exist, I can only find that highly irrational and ridiculous. If I were to speculate as to why you believe in it, well a lot of people in MA are in awe of Eastern philosophy and culture and are looking for something different to their own experience. Maybe that is your situation, maybe not. maybe you would like to think that Aikido or tai Chi or whatever can give you special powers. Sorry but they cannot.
Whilst you are getting upset, you have failed in any way to offer the tiniest reason why anyone should believe that chi exists or why anyone would believe that kata heals.
"How very unscientific."
You believe in chi, something that ranks in credibility alongside the tooth fairy. Yet you insist it exists. What is that if not superstition? You offer no science to back up chi (how could you, it is nonsense!) and get upset when you are called on it.
