Analisa Wingfield (2022-04-20)

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 longer than men, and why does this benefit increase over time? We have only a small amount of evidence and the evidence is not sufficient to support an informed conclusion. We are aware that behavioral, biological and environmental factors play a role in the fact that women live longer than men; However, we're not sure how significant the impact of each of these factors is.

Some are well known and relatively straightforward, like the fact that men smoke more often. There are others 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, ماذا يحدث بين الزوجين في الحمام بالصور especially for survivors, ended up raising women's longevity disproportionately.

The advantage of women in life expectancy was less in rich countries as compared to the present.
Let's see how the female longevity advantage has changed in the course of time. The following chart shows the life expectancy of males and females at birth in the US over the period 1790-2014. Two areas stand out.

First, there's an upward trend. as well as women in the US live a lot, much longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.
