Why Women Are More Likely To 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. What is the reason women live much longer than men today and why has this advantage increased over time? The evidence is sketchy and we only have partial solutions. We are aware that behavioral, biological and environmental factors contribute to the fact that women are healthier than men; but we don't know exactly how significant the impact to each of these variables is.
It is known that women are living longer than men, اضيق وضعية للجماع regardless of weight. However this is not due to the fact that certain non-biological factors have changed. What are these new factors? Some are well known and relatively straightforward, like the fact that men smoke more often. Others 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 اضيق وضعية للجماع survivors, ended up raising women's longevity disproportionately.
