According to tradition, when an Eskimo hunts a wolf, the first thing he does is coat his knife blade with animal blood and allows it to freeze. Then he adds layer after layer of blood. He then puts his knife in the ground with the blade up. The wolf follows his nose to the source of the scent and begins licking it, tasting the fresh frozen blood. He begins to lick faster, more vigorously until the edge is bare. Harder and harder the wolf licks the blade. His craving for blood becomes so great that he doesn’t notice the razor sharp sting of the naked blade on his own tongue. Nor does he recognize when his insatiable thirst is being satisfied by his own warm blood. His tongue has become desensitized. His appetite continues to crave more until in the morning light the wolf is found dead in the snow.
