Subtitled Unleashing the Power of Consciousness, Matter and Miracles, it's a book that brings attention to the new awareness that is rewriting the science of biology (and medicine).
The main argument in the book is that genes do not control life. It is our perception of the environment that controls gene activity.
In the end, it comes down to a simple case of 'mind over matter' in controlling the fate of our lives. That's something we long distance runners should probably find easy to believe.
