I dont think its up for discussion when the natural ages a women should have children are. Thats nature. There are all sorts of ages, but they come with added dangers.
During the 50s, 60s , 70, 80s after highschool many people then were mature enough to get married, have children, and hold a job and mortgage.
College was not popular.
And during those times, men were men and women, women.
They produced a very strong and patriotic off spring.
Now today, people wait until very late to start families, girls look and develop more like boys and boys develop and look more like girls.
Patriotism is at an all time low
Grip stength among children is way down, lol. Read a study where kids are physically getting weaker.
