I think the argument on chi is pretty silly. Whether it does or doesn't exist doesn't matter. It's symantics really. When I do my techniques and incorporate the "Ki" aspects of them they work better, period. So, why does it matter if you call it Ki, Qi,Chi, proper body mehcanics/physiology/kenisiology, etc? If you get the desired results, I don't see the point of arguing the terminology of common experiences. One person sees magic, one person sees tricks, one person sees good form in technique, and one sees internal connections of energy to the universe at large; they're all right if they get the results they were aiming for.

Just MHO. Had to chime in because it seems like this argument is perpetually started and restarted and renamed. I don't see the point in continuing arguments so heatedly about what I see as a fight over what the correct name of these functions are.
