Who's the Brainiest of Them All?

It appears that the matter has been settled out of court, and right-handed males lose.

Neurologists at the University of Pennsylvania conducted studies of blood flow through eight regions of subjects' brains while they were performing mental tasks, and found that the flow rate was highest in women and in left-handed people.

Since gray matter, found mostly in a quarter-inch layer on the surface of the brain, is largely responsible for intelligence and also conducts the most blood, the conclusion was inescapable.

So men, if you have a left-handed wife who also happens to be a woman, better let her balance the checkbook.
