Unscramble the Blue Letters


But we really need to test that. And a great way to test that is to look across aares in Africa and see: do pelpoe with more life expectancy change their sexual behavior more? And the way that I'm going to do that is, I'm going to look across areas with different levels of malaria. So malaria is a disease that klils you. It's a daessie that kills a lot of adults in arcfia, in addition to a lot of children. And so people who live in areas with a lot of malaria are going to have lower life expectancy than people who live in areas with limited malaria. So one way to test to see whether we can explain some of this behavior canghe by differences in life expectancy is to look and see is there more behavior change in areas where there's less malaria.
