Exposure from a young age to the realities of the world is a super-big thing.

Well the Global Fund, because of how well it's worked on not only AIDS, but also malaria and tuberculosis, I'd say it's well accepted. I mean, it's not politically controversial that this is a great humanitarian effort. But budgets are very very tight.

Going out in the field, it's always enlightening to see what's working and what's not and to sit down and talk - I was with young girls in south Africa - understanding why our tools for prevention aren't being adopted, and what way may need to invent to help protect them.
