The human body is an amazing place. The study of it's anatomy and physiology is exhaustive and ongoing and we only need to cover a morsel of it here.
Typically the study of the human body has it's difficulties. Scientists like to classify things, it allows complex systems to be understood in terms of their components, a system inherited from the Greeks and one that has it's advantages but can compromise how we study people. Since DeCartes medicine has become a science and taken on the Greek legacies. It has yet to catch up with Einstein but that's another story.
The basic problem is that they are not separate components, they neither function separately or make any sense separately. The reason that we understand as little as we do about the human condition is that we are still to come to terms with exactly how everything is connected but there are a few things staring us in the face.
Our posture is the most obvious example of the totality of the human body. We finally become a three dimensional shape rather than a series of components. By extension this three dimensional shape changes in response to not only physical tension but any of the many types of stress that we are subject too. This is why the relaxation program is so important and equally why we are all aware of the importance of being physically relaxed as we play.
