For most of human history, we have not needed to wonder who lives longer: men or women? However, towards the end of the 19th century, women suddenly began outliving men
There are many hypothesized reasons why women live longer than men. Therefore, this has been a fascinating area of research for many scientists.
With advances in clean water, antibiotics and education about nutrition, humans began living longer. But despite the changes that the 20th century brought, men still lagged behind women in life expectancy. Did the industrial revolution only benefit women?
Animals studies, however, showed some interesting counter-arguments to that. While the human animal is somewhat unique with its females outliving males, other species vary widely. Except for the apes. They obviously did not create for themselves an industrial revolution, but their females outlive males.
