Re: Why do you perceive "internal" superior to athleticism?
I didn't mean that the article itself was the "in-depth" study -- it was just to provide some reference about what the chief researcher was doing beyond the students who made the video above.
My point, basically, was what Mark Murray was saying in post #307: That there are a number of "things" happening in the body that cannot be observed in the way that your linked article explains an observable sequence or linear chain of "events." IP is not one discrete action or function that can be traced to one physiological event.
The tools for scientific inquiry don't exist yet for this area, probably because Western science hasn't gotten its meathooks into it yet. Like I said, it's still below the radar. The Stanford study is one of the first I've heard of, and they seem to be few and far between.
