Autumn babies more likely to hit 100

7. The big question is,

will that autumn birth longevity effect still hold forty years from now when I turn 100, or 100 years from now for the babies born this year.

I think conditions of pregnancy and in the period immediately after birth have changed so very much in the past century that those findings, while quite interesting, cannot be used to predict who born, say in the past 50 years, will live so long.
