Man,
Once again I expect some authority types to check this out??
Then of course there is many factors involved.
Type of feed? good steaks or maybe gub mint crap?
Work habits? worked hard or on public dole?
Breeding? come from takers or workers?
See there must be many grades of PEOPLE MEAT!!!
I think all the People's Meat has been consumed (vermin/snakes etc). This grading system won't occur until the army and elite start using the people as meat. Probably not so far off for that benighted place.
