Earlier quoted context omitted.
The best age for having kids biologically, in terms of health is... Close to 18. I had my first child when I was 27 and I was already very tired in the nights, we agreed with wife that it would have been better to start earlier. Some people have kids when 35-40 and I cannot imagine it at all. I'm too tired right now. Much wiser, but my health would not allow me to stay up nights
Biologically yes... Probably but maturity, stability wise closer to 30-35 seems to be pretty good. At least the going rate amongst my friends
My wife's mother had her when she was 20. She's still around, got to see her grandchildren reach adulthood, and have a long relationship with her daughter as an adult.
