The life expectancy of a man who has already reached the age of 51 however, is 82, because that average no longer includes deaths of younger men. If you add things like good health, education and higher income, which are likely for someone that decides to have kids at 51 (and that manages to find a most likely younger partner willing to have kids with them), then one might lose their parent at the age of 35. It's still early but not uncommon.
