I'd like to know how many people would eat human meat if it was not so taboo (No nervous system so as to avoid nasty prion diseases). I know that since I accidentally had a bite of finger when I was about 19 that I've wondered what a real bite of a person would taste like (prepared properly... Maybe a ginger/garlic sauce???).

Also, building on Kaj Sotala's proposal, what about sexual assignment by job or profession (instead of biological sex). So, all Doctors or Health Care workers would be female, all Soldiers would be male, all ditch diggers would be male, yet all bakers would be female. All Mailmen would be male, yet all waiters would be female.

Then, one could have multiple sex-assignments if one worked more than one job. How about a neuter sex and a dual sex in their as well (so the neuter sex would have no sex, and the hermaphrodite would be... well, both...)
