These stats are usually skewed as they don’t remove infant mortality from the data. If you remove people who died before the age of 2 the gap is not nearly as wide.

Modern medicine has reduced infant mortality greatly, for which I’m grateful, but those who survive early childhood really don’t live that much longer.
