The true story is told how an Eskimo kills a wolf. An Eskimo is a member of the very cold northern areas of North America, Russia and Greenland.
He coats his knife-blade with blood and let it freeze. The he adds another coat of blood and let it ten another. As each coat freeze, he adds another smear of blood until the blade is hidden deep within a substantial thickness of frozen blood. The he buries the knife-blade up in the frozen tundra. The wolf catches the scent of fresh blood and begins to lick it. The wolf licks it more feverishly until the blade is bare. Then he keeps on licking harder and harder. Because of the cold, he never notices the pains of the blade on his tongue. Its craving for the taste of blood is so great that he does not realise its taste has been satisfied by its own blood. It licks the blade till it bleeds to death, swallowing its own life.
