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 much longer than men today and why have these advantages gotten bigger in the past? We have only a small amount of evidence and the evidence isn't sufficient to support an unambiguous conclusion. While we are aware that there are biological, behavioral as well as environmental factors which play a significant role in the longevity of women over males, it isn't clear what percentage each factor [https://glorynote.com/%D8%A3%D8%B6%D9%8A%D9%82-%D9%88%D8%B6%D8%B9%D9%8A%D8%A9-%D9%84%D9%84%D8%AC%D9%85%D8%A7%D8%B9/ اضيق وضعية للجماع] plays in.<br><br>In spite of the weight, we know that a large portion of the reason women live so much longer than men do today but not previously, is to relate to the fact that some important non-biological aspects have changed.
