We know that biological, behavioral and environmental factors contribute to the fact that women are healthier than men; However, we're not sure how significant the impact of each factor is.

In spite of the precise amount of weight, we are aware that at least a portion of the reason women live so much longer than men do today but not previously, is to do with the fact that certain important non-biological aspects have changed. What are these new factors? Some are well known and relatively straightforward, like the fact that men smoke more often. There are other issues that are more intricate. 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.
