I flopped down on the bed, flipped on the T.V. and saw a BBC documentary that would change my life. One sentence spun my brain: “Did you know that every day 3,000 children in Africa die of malaria, needlessly?” Turns out if sub-Saharan African kids six and under could just sleep under bed nets, they’d be almost entirely protected from malaria-carrying mosquitos. They might die of something else, but not malaria. And a net is only $10, the announcer said.
