First, let me say that I am not a medically trained person. Have read quite a bit of medical stuff, but as they say, that reading and 3.50 will buy me a cup of coffee at Starbuck's. And I'm quite sure that those who know more about this topic will add much more (please flame gently). Here's my theory: from the beginning of mankind (OK, people kind if you are too sensitive) our bodies were designed to do physical work, generally outside, but physical nonetheless. This went on for kajillions of years: working hard outside, killing the occasional bear, dying of relatively minor infections by today's standards, eating food that would support that kind of lifestyle. Then, roughly, 70 - 100 years ago (pick your date) which was at the very tail end of our existence - probably representing a tiny fraction of our existence, everything changed. This was a good thing. Specialization of labor. Industrialization. Time for the Arts. Personal productivity skyrocketing. The bad news is that we were stuck with these low tech bodies designed for hard work, killing the occasional bear, and meant to be used up at, say, 50 years of age. The posterior of which was hardly used 10,000 years ago, and now it's the butt of all kinds of jokes as well as admiration in some quarters. Again, I'm no anthropologist, but I've never seen cave drawings in which the characters are sitting. They probably exist somewhere. And, now instead of dying from simple infections, we die from not using the heart enough or some other part that really wasn't designed to last as long as we want it to in today's world. So, what's the answer? About another kajillion years of evolution in which we lose some fingers, our head gets bigger, our legs become tiny spindly things - I don't know about the butt, etc. Anyway, that's my $.02 worth. Have a great week everybody! Ken (Rohr, Dreher, Staab) Worry looks around, sorry looks back, faith looks up.
