Why women are more likely to live 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 main reason women have a longer life span than men? And why has this advantage gotten larger over time? The evidence is limited and we only have incomplete solutions.
