Since July 1, 1970—just one of many lucky days in my life—when I learned that the draft lottery for military service in the Vietnam war had assigned boys born on my birthday a safe 163rd out of 365, I have wondered how I would have handled the traumas of combat.  Now that I treat my age mates at the VA who were less lucky than I, I can’t forget about the question.  Would I have been among the one in six exposed to combat trauma who would later develop post-traumatic stress disorder(PTSD)?
