“When this curve was compared with a curve showing changes in reproductive potential over the life cycle (a pattern calculated from Canadian demographic data), the correlation was fairly strong. But much stronger—nearly perfect, in fact—was the correlation between the grief curves of these modern Canadians and the reproductive-potential curve of a hunter-gatherer people, the !Kung of Africa.”
Can someone clarify this? What is this? At first I thought that it’d be the expected number of kids one would have over the rest of their life, but I don’t see how that could go ever go up.
