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 live longer than men in the present, كيفية ممارسة العلاقة الزوجية فى الاسلام - glorynote.com, and why is this difference growing over time?
