The study, the first of its kind, was based on a single subject: University of California, Irvine cognitive neuroscientist and study co-author Elizabeth Chrastil, a first-time mother who gave birth to a healthy boy, now four and a half years old. Chrastil was 38 during the study, and 43 now.

This woman is very old for a first pregnancy.

I don’t think that this study would necessarily present data that is typical for a mother of a more typical first pregnancy age of 16 to 22.

[Valpal1]

16-22 is no longer the typical age of first birth.

[ansel12]

“”””more typical first pregnancy age of 16 to 22.””””

So far, you appear wrong on that.
