Why Are Women Living 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's the main reason women live longer than men? Why is this difference growing as time passes? The evidence is sketchy and we have only partial answers. While we are aware that there are biological, behavioral and environmental factors that all play a role in the longevity of women over men, we do not know how much each one contributes.

We have learned that women live longer than men, regardless of weight. However this isn't because of certain non-biological factors have changed. What are the factors that are changing? Some are well known and relatively straightforward, like the fact that men smoke more often. Others are more complex.
