Bill Gates, Philanthropist

Bill Gates is the world's third-richest person, and the driving force behind the vastly-endowed Bill & Melinda Gates Foundation -- which is concerned primarily with global health and education issues. Two days ago, Gates gave a great talk on the problems his philanthropy is tackling. The talk is remarkable first because he's actually a terrific speaker and knows his topic...but also because he released a small swarm of mosquitoes into his audience:

"Now, malaria is, of course, transmitted by mosquitoes," said Gates. "I brought some here, so you could experience this. We'll let those roam around the auditorium a little bit." [Releases mosquitoes.] "There's no reason only poor people should have [this] experience."

The mosquitoes were not malarial, but still. Wow. Have a look at his talk to learn about the work Gates is doing on health issues around the world.
