GATES: Well, I looked at what is the greatest inequity in the world. The U.S. is very oriented towards solving inequity -- gender inequity, racial inequity. In fact, you'd have to say, the great inequity is that we let people die of these diseases. We treat their lives as being worth less than a few hundred dollars because that's what it would take to save them. And so there's a huge disparity and bringing the advances in science to those diseases can change that in a big way. So, my goal was to pick the thing I thought was the greatest inequity in the world, focus on that as our top priority and that's world health and then take the greatest challenge for the United States and make that also a priority and that's the work we're doing in education.
JENNINGS: Many thanks. I enjoy listening to you.
