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 longer than men, and why does this benefit increase in the past? The evidence isn't conclusive and we have only partial solutions. We are aware that behavioral, biological and environmental factors all play a role in the fact that women have longer lives than men, but we don't know exactly what the contribution to each of these variables is.

In spite of the number of pounds, we know that at a minimum, the reason why women live so much longer than men in the present, but not previously, has to have to do with the fact that certain key non-biological factors have changed. What are the factors that are changing? Some are well known and ماذا يحدث بين الزوجين في الحمام بالصور (https://Glorynote.com) relatively straightforward, like the fact that men smoke more often.

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.

Let's take a look at how the female longevity advantage has changed over time. The following chart shows the men and women's life expectancies at the birth in the US from 1790 to 2014. Two distinct features stand out.

There is an upward trend. and women in the US are living much, much longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

And second, there is an ever-widening gap: female advantage in life expectancy used to be quite small however it increased dramatically over the course of the last century.
