In this very interesting 20 minute talk by Mr. Bill Gates, I learned, for example, these 3 things:
# 1: The number of children who die before the age of five has been reduced considerably over the past years. But still today, several million children die each year before the age of 5.
# 2: More money is put into baldness drugs than is put into malaria.
# 3: Education is the most important thing to get right for a country to have as strong a future as it should have.
