Do most people really live like that in their twenties? Getting laid all the time, unstable relationships and so on? I kind of thought that there was a lot of media hype in that story.

Anyway, I think the main thing is that having kids in your thirties is a lot more stressful, in the sense that you usually want to have a stable relationship before having kids together, and time is running out. There is that biological clock ticking, at least for women - while men have more options, it means having to find a significantly younger woman to have children with.

And once you have children, you realize that it would have been nice to be younger. It means being in better shape to play with your kids, being able to be there for them longer, and a higher chance to experience grandchildren.
