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 reason why women have a longer life span than men? And how the advantage has grown over time? There isn't much evidence and we're left with only some answers. While we are aware that there are behavioral, biological, and environmental factors that play an integral role in the longevity of women over males, we aren't sure how much each factor contributes.
In spite of the precise amount of weight, we are aware that at least a portion of the reason why women live so much longer than men and not previously, صبغ الشعر بالاسود has to have to do with the fact that several fundamental non-biological factors have changed. What are these factors that have changed? Some are well known and relatively straightforward, like the fact that men smoke more often. There are others that are more intricate.

The first chart below shows life expectancy at birth for men and women. We can see that all countries are above the diagonal line of parity - this means in all countries that a baby girl can be expected to live longer than a newborn boy.1

Second, the gap is getting wider: Although the advantage of women in life expectancy used to be tiny It has significantly increased over time.
