 Well, you know, I admire different people in different fields. I tend to admire people who are doing things that I may have liked to have done, but I took a different pathway. I mean, I could just think of one person that has, to my great satisfaction, has turned out over the years to be a good friend of mine who does things that are extraordinary in his self-sacrifice for the good of mankind is a person named Paul Farmer who is an anthropologist physician who at great self-sacrifice of worldly things has done things that have opened up the door to helping really literally millions of people. I mean, he went to Haiti and established a health clinic there that's the model of how you deliver care in a rural setting and it was Paul's model that actually inspired me to come back from Africa and tell the President of the United States that we could do this in the bush because there have been examples of people like Paul Farmer who've gone in and delivered therapy to the poorest people who you didn't think you could get therapy to. So, I mean, I have a great deal of admiration for him among a variety of other people. Well, if you want to get involved and be a player and make a contribution, you try as best as you can to fashion your training, to give you the flexibility to get into a particular field. Science is not for everyone. You've got to do what it is that excites you. I have the same situation with my own children to try and prevent myself from being a little bit too enthusiastic about going into a particular field. The only thing I could say to young people who are thinking about careers is that science, if it suits you, is wonderful because it's discovery. There's something so exciting about the discovery of something or being part of a group that helps discover something or you discover something that someone else uses and ultimately it's for the betterment of mankind and health. I happen to be in the health arena of science. Science goes well beyond just health. And as the question you asked me early on is that what got me involved with it was an affinity for wanting to do something for humanity in a public service. And since I was interested in science, interested in discovery, I evolved towards a career in not only medicine but in discovery aspects of medicine and science. So I would just encourage younger people to go with your gut and what you like and what excites you. If it turns out to be science and biological sciences and health, great. If it doesn't, that's okay too, as long as you do something that you feel good about and that you're excited about.
