Never say die?

I’m not sure what to expect out of this story of a guy who, left behind in a crazed state and presumed to have died, overnighted above 8000 meters on Everest and was found alive the next day, prompting a rescue effort expected to take three days.
(Note that this is a different climber from the one who really did die after being left behind as beyond hope a few days earlier.)
Update 5/27/2006: He made it. Said to be suffering severe frostbite and cerebral edema (HACE).
