I would suggest this as a very sane new division of humanity. Easily verified membership, totally voluntary, completely different value systems and motivations.
Finally a rational way to be prejudiced! "I just don't get along with Aerobians."
Or, "Those Sedentarians drive me nuts!"
A better bigotry for a better, more correct..political correctness! Excellent.
