When I was a sophomore at the University of Texas. I was invited to visit a friend down in San Antonio, who was an intern at the time, working at a municipal hospital there. And he asked me to come over and join him on a Saturday night when he was working in the emergency room. And he had all of these patients there who were all beat up, cut up, or so on, in fights and so on. And he offered me the opportunity to sew up some wounds, which I had never done. And sure enough, I did that, and I enjoyed it, enjoyed the evening. It inspired me, and right then I decided that I would go on into medicine rather than into dentistry. So here I am.
