Whenever I look back over my long career, I think about why I went into healthcare. For me, it was because I loved chemistry and biology, and helping people. And that's the truth. I can't see myself doing anything else because, as I always say, if you don't have your health, you don't have anything. Why did you get into what you do? Was it because you really wanted to help people, or was it just because you didn't think of anything else?
