Taking the plunge

How on earth did this guy not die when he went over Niagara Falls all by his lonesome, without even a barrel. Not only did he come away from the plunge over Horseshoe Falls but he surfaced where rescuers could see and reach him, avoided freezing to death during 40 minutes in the late winter waters, and came away with only a few broken ribs and bruised back. Efforts to save him were no less heroic than Clark Kent's.
