In medical school, you’re required to memorize a body of facts. You go to gross anatomy, and you learn what muscles attach where and what goes where. You memorize it. When you go into the research lab you’re creating new knowledge, and it was play for me. It was like doing art, or writing poetry, or painting on a canvas. So it wasn’t work. When I was in the research lab from 2:00 to 4:00 o’clock in the morning, it wasn’t work for me. It was play. It’s what I enjoyed doing. Now for someone that didn’t like research it would be really hard work, but for someone who enjoyed it, it was fun.
