I had no specific bent toward science until my grandfather died of cancer. I decided nobody should suffer that much.

~ Gertrude B. Elion

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.
