Apparently I was wrong - according to this

https://www.ncbi.nlm.nih.gov/m/pubmed/16510865/

But this study is contradicted by many studies

the radiolab is from 2012, and i'm sure they've learned a lot since then, but they do mention that there are a lot of factors (sex of children, number of children, number of fathers) that correlate with both good and bad effects of the fetal cells.

So which is it?

Do children at 20-30 increase or decrease life span?

Obviously people who live longer may have more children, especially the men. I am talking about the other way.

The simple answer is its complicated. Having a child is stressful on the organism, but there are ultimately 2 types of stress eustress and distress.

Sometimes it's good sometimes it's bad. ¯\_(ツ)_/¯
