Over the years, my work became both my vocation and avocation. Since I enjoyed it so much, I never felt a great need to go outside for relaxation. Nevertheless, I became an avid photographer and traveler. Possibly my love for travel stems from the early years when my family seldom went away on vacation.

I think it's a very valuable thing for a doctor to learn how to do research, to learn how to approach research, something there isn't time to teach them in medical school. They don't really learn how to approach a problem, and yet diagnosis is a problem; and I think that year spent in research is extremely valuable to them.
