Wow! Someone needs to go explain to them that a survivalist doesn't try to push himself to the edge of death. Instead he does everything possible to stay as far away as possible from the grim reaper. I'm an amateur if you are talking about building fire from nothing or finding water in the desert, but hiking in the heat with little water is down right retarded - IMHO. They should have been training them to stay in the shade during the heat - then look for water & head for rescue when it's cooler. Amazing.
