Just think of the advantages. For one, people would really be equal in a fundamental way. No one would be slighted in one category without a compensatory increase in others. If you saw someone on the street with no legs, you could be sure that they had plenty of other skills or abilities to make up for it. Likewise, if you bumped into someone who had a mind like albert einstein, you could be relatively sure that he was a 90-pound weakling, would fall over trying to skip, or had some other deficit. It would be one way to reach that goal of different but equal that's often so plagued society.
I wonder if I should send the Pope a copy of the PHB and see if he can broach the idea with God.
