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 much longer than men today and how have these advantages gotten bigger over time? There isn't much evidence and we're left with only incomplete answers. We know that biological, behavioral and environmental factors all contribute to the fact that women are healthier than men; however, كيفية إقامة علاقة بالصور we do not know how much the influence of each factor is.

In spite of the precise number of pounds, we know that at least part of the reason why women live longer than men do today however not as previously, is to relate to the fact that a number of fundamental non-biological factors have changed.
