What is it that makes us get sick? Many years ago there was a painkiller commercial on TV that showed a big hammer hitting someone in the head. The hammer stopped whacking him when he took the right pill. That’s the picture most of us grew up with, that disease and bad health are things that just happen to you, and if you take the right drug (or get the diseased parts cut out) you will miraculously become well. Cause was never even considered. But there must be a cause other than bad luck or lousy genes. The fact is that diseases usually start because of a breakdown of the function of one or more parts of our bodies. Although it can relate to genetics, trauma, infection, or poison, often this breakdown of function happens because of inappropriate or suboptimal lifestyle choices we have made, and continue to make, or that are made for us.
