As a point of interest, I just found this article by Ian Deavin in the Longfei newsletter, Vol. 6, Nos. 1 & 2. It describes some biomechanical models for applying and absorbing force. I liked the pictures and found the descriptions helpful.
Kal, Good stuff to contemplate on. I'm not sure I agree with everything, but it all made me think. I'll take a longer, much closer look at these articles than I can now when I get some free time. Thanks for posting them.
