Why Do Women Have Longer Lives 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 have a longer life span than men? Why has this advantage gotten larger as time passes? We only have partial evidence and the evidence is not sufficient to support a definitive conclusion. We are aware that behavioral, biological and افضل شامبو وبلسم (please click the following internet page) environmental factors play a role in the fact that women live longer than men; However, we're not sure how strong the relative contribution to each of these variables is.

We are aware that women are living longer than men, regardless of weight. But it is not due to the fact that certain biological factors have changed. What are these changing factors? Some are well known and relatively straightforward, افضل شامبو وبلسم like the fact that men smoke more often. There are others that are more intricate.

The advantage for women in terms of life expectancy was lower in developed countries that it is today.
Let's examine how the female longevity advantage has changed over time. The following chart shows the men and women's life expectancies when they were born in the US between 1790 to 2014. Two points stand out.

There is an upward trend. Women and men in the United States live longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

The second is that there is an increasing gap: The female advantage in life expectancy used be very small however, it has increased significantly over the course of the last century.
