In a previous report, we made the point that people are really different. Some are made of steel and indestructible, others of glass and break easily. The question is why? We have shown by example several resistance and susceptibility factors. All of this, put together, represents metabolism, often referred to as homeostasis, balance or harmony. These are highly measurable and mappable phenomena and we must look into the thousands of physiocochemical reactions that accompany them.

The strategy and tactics of the medical system take on new and different meanings once one accepts the fact that homeostasis, the steady state, may well be the centerpiece of our problem. Claude Bernard, Walter Cannon, and other pioneering researchers gave us this fundamental concept.^1,2 What does it mean?
