7 months agoEverywhere in the world women live longer than men - but this was not always the case. The available data from rich countries shows that women didn't live longer than men in the 19th century. What's the reason women have a longer life span than men? And why is this difference growing as time passes? There is only limited evidence and the evidence isn't sufficient to support an informed conclusion. We know there are biological, behavioral and environmental factors which all play a part in women who live longer than men, we do not know how much each factor contributes.

In spite of how much number of pounds, we know that a large portion of the reason why women live so much longer than men do today however not as previously, has to relate to the fact that some 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. Some are more complex. 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.
