Why do women live longer than men?

Everywhere 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. Why do women live much longer than men today and how is this difference growing in the past? We only have a few clues and the evidence isn’t sufficient to reach an informed conclusion. We recognize that biological, behavioral and environmental factors all play a role in the fact that women are healthier than men; However, we’re not sure how strong the relative contribution of each one of these factors is.

In spite of how much amount of weight, we are aware that at a minimum, the reason why women live longer than men do today however not as in the past, is to do with the fact that a number of important non-biological aspects have changed. What are these factors that have changed? Some are well known and relatively straightforward, Glorynote.Com/%D8%A7%D9%84%D8%A7%D8%A8%D8%B1%D8%A7%D8%Ac/ 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.
