Actually, now that I think about it, that'd be awesome. I could finally be good at Basketball, and no one would mess with me. Plus I could carry around a club and raise mammoths.

I'd make states into institutions. At 15 years of age, a person is mentally and physically tested and thrown into a sector based on their results. Therefore, people would be around people they like.
