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.

First, there's an upward trend. Both men and ابر التخسيس - glorynote.com - women in the US are living much, much longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.
