Eons ago when I was a child the school nurse told my parents I would never be a pilot. I have lousy depth perception. So I am sure that a lot of things could pop up in a physical that could mess a guy up.

My point was that the physicals were not that complicated and they had forwarning of them. That means that if the president was a cocaine addict [which is the vervent dream of all Bush haters] he would have time to clean up his system and pass a physical unless there was some real medical problem there in which case it would have no real bearing 31 years later.
