It used to be that a lot of people joined religious orders that required chastity. Many of those orders did wonderful things for their communities (scandals aside). My mother and grandmother had all kinds of fun stories about the nuns who ran their school. I agree, it kind of makes sense for some people to abstain from creating children, so that there are more adults available to help raise them. And as you said, those who don't have children can still have a vibrant family life.

Cute story about the blonde baby!
