You don’t have to. Turns out, when you give women the option to not shove a watermelon-sized object through their hoohaws at an age when they’re not ready for it, many of them opt not to!

Curiously, it worked too well. China is now desperately offering incentives to get people to have more children.

(Okay, I’m just being glib. It’s not clear whether it was the one-child policy that was responsible for the birth-rate crash.)
