Being mauled by a bear would be one of the worst things I can think of. The wounds would get horribly infected no matter how they cleaned them. The recovery would take a long time.
Jack O'Connor relates a tale about a guy named Field Johnson that was mauled. He did the "play dead" thing, but the grizzley wasn't far off. Johnson got up after what he thought was a reasonable amount of time. Bear went berserk and mauled him again and buried him. Johnson survived, but went insane. And wounded black bears are supposed to be worse. They don't so much maul you, as tear you into small pieces.
