Immediately after college he went into the Marine Corps and was highly decorated for his service in Vietnam as a second lieutenant.

It was time to solve his problem with post-traumatic stress disorder a problem the VA told him he would have for life. Bob spent years learning how the brain processes and retains information. He learned that the brain was plastic and capable of making changes throughout life. Understanding the problem allowed Bob to face it head on and put the war behind him. This work also to led understanding how the brain learns and directs the coordination of motor skills which he explains in his second book on golf.
