What's the reason women have a longer life span than men? And how has this advantage gotten larger as time passes? There isn't much evidence and we have only limited solutions. Although we know that there are behavioral, biological, and environmental factors that all play a role in women's longevity more than men, we don't know how much each factor contributes.

These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. Other are more complicated. For example, there is evidence that in rich countries the female advantage increased in part because infectious diseases used to affect women disproportionately a century ago, so advances in medicine that reduced the long-term health burden from infectious diseases, especially for survivors, ended up raising women's longevity disproportionately.
