We start with an economic approach. We look at what are the greatest causes of death in the developing world, and what causes the largest amount of disability, which would prevent you from getting a job. A lot of those deaths start with diseases, diseases we don't get in such a great number in the United States.

We started our foundation because we believe we have a real opportunity to help advance equity around the world, to help make sure that, no matter where a person is born, he or she has the chance to live a healthy, productive life.
