The higher the life expectancy in a society, the smaller the difference between the ages at which people will die. This relation can be described by a mathematical rule, as demographic data from many countries show. The relationship holds not only for very different human cultures and epochs, but similarly for non-human primates. Although separated by millions of years of evolution, for both humans and non-human primates the lives of females tend to be longer than the lives of males, suggesting deep evolutionary roots to the male disadvantage.
