In short, I devoted myself to science. Using the tools of modern medicine to help and to heal people, and to learn more about the workings of the human body and brain, was my life’s calling. I felt immeasurably lucky to have found it. More important, I had a beautiful wife and two lovely children, and while I was in many ways married to my work, I did not neglect my family, which I considered the other great blessing in my life. On many counts I was a very lucky man, and I knew it.
