You've probably heard about the gender gap in human life expectancy. According to the United Nations Department of Economic and Social Affairs, females worldwide live an average of 73.5 years, while males average 68.5. Those figures can vary pretty drastically (life expectancy for both men and women is still less than 55 years throughout much of sub-Saharan Africa), but the last several decades have seen large gains in life expectancy across the globe, for men and women, alike. Still, the gender gap persists*. "Wherever they live in the world," reported the World Health Organization in 2014, "women live longer than men."
