Fifty times the amount spent on researching malaria goes to finding a cure for baldness.
So, according to the Economics I learnt in school, the demand for a vaccine for malaria is lower than a cure for baldness, which in turn means that more people are bald than those who are infected with malaria.
p.s. - Sorry for the lack of explanation elaboration, I'm just too indulged in something called the Internet to care. LOL
