The human body is just so poorly designed! If the so-called Intellegent Design Theory is correct, how come the design is so damned poor? Backs and knees are extremely poorly designed. They fail on almost everyone in less than the expected human lifetime. I really don't think that you can call that intelligent. It would really take very little to make all the human musculoskeletal structure much better than it is, make us all extremely athletic. Nobody with any intelligence would have designed in the possibility of becoming morbidly obese, yet a large percentage of Americans are just that. And the percentage is increasing.
What brings all this up and makes me so testy about it is that my back is acting up again. I've learned exercises and things to avoid to keep it in line, but it periodically ignores all my careful tenderness and lets me down anyway. Oh well, we are born to suffer, and then we die. --gk
