Even people with
less than a high school education today recognize the
priority of the brain over the blood, so much so in fact, that in the movie, Hannibal (about a cannibalistic serial killer), the thought of slicing out tiny parts of a person's brain, cooking them in a pan, and serving the pieces to that person to eat has become in the public's mind a more disturbing image than, say, serving a person a glass of their own blood to drink, which appears
relatively tame in comparison.
