He was a supersonic fighter jet pilot during the Cold War era. You can't get much more manic and righteous and obsessive than that.
He destroyed his front teeth sucking on lemons as a teenager.
He had some "impulse control problems" that persuaded him to choose a military career over time in a Texas prison. (Read hot-wiring the sheriff's car and taking his friends for a ride in it...)
Notably, he also experienced a rapid increase in nasal infections and dementia after having them capped late in life.
