Robert, body=machine is only an analogy, and a very inexact one.

Newtonian Physics is a very ‘exact’ science. Where does Newtonian Physics not apply in biology? You cannot say fluid will not pass through this diameter hose in hydraulics; but it will in biology – without specifying why there is a difference.

There is, obviously, a difference between what happens in mechanics and what happens in biology. We need to find that ‘something’ that allows that difference. It seems to me there must be some sort of quantum physics that applies to biology.
