I knew people like that in Vietnam. Jack Patton had that sort of courage. I could be as brave as Jack over there. In fact, I am pretty sure that I was shot at more and killed more people. But I was worried sick most of the time. Jack never worried. He told me so. I asked him how he could be that way. He said, ‘I think I must have a screw loose. I can’t care about what might happen next to me or anyone.’
