Yeah that's bullshit. You just need to grab them when they're relatively uncorrupted. I don't care what age you are. If you're single and want more kids, go woo college freshman girls and rescue them from genocidal social programming. You can't find an ideal woman, but you can find excellent material and shape her into an ideal mother. So fuckin do it, instead of focusing on all the 100-body count sluts in their late 20s, which are beneath us.
