Eli5: Why do women live longer than men on average, even among the older population like supercentenarians?

Answer 1

As corrected by u/TheLandofConfusion:

The X chromosome contains more coding genes than the Y chromosome. Women have two X chromosomes. If one malfunctions/is damaged, there is another to compensate, unlike men who only have one X chromosome. Other theories is that the Y chromosome is actually harmful. And as other posters have stated, there may be cultural or environmental variables which skew data.
