When Fire-Dragon-DoL writes >That 5 years difference between men and women keeps being biologically weird The implication is that the "biological" expectation would be that men and women have the same life expectancy, absent medical intervention and societal standards and whatnot. But it is possible that, due to having different biologies, men and women simply have different life expectancies. Similar to how men and women have different muscle mass and bone densities and height and yada yada. Obviously, external factors could also be a factor, but my point is "internal" factors are also in play.
