The tv show ort to be called Bear Grylls extreme evations. Has nothing to do with "survival" or living in nature for an unknown period unto social security is reestablished.
I wont even go into details as almost everything he does on cam is explortation tv, eating bugs, cheating death and raw action. Ill just highlight rule number one of "survival": DONT GET INJURED, which he purposely breakes all the time and in the best cases only leads to fatigue. A state he reaches far more often than the clips on he's tv shows seems to reweal, but that the trained eye clearly spots. Using he's tehnicques will steadely increase your risk of getting injured for every step you take!
The only way i would use any of he's techniques in "survival" was if i was being huntet.
I beleave there is a straight line from the above to the man in the mud, as "survival" rule nr 1 would not have let him to enduse an overdose of alcohol, crosing unknown territory, with known dangers, in the dark while presumble somewhat fatigued and alone. I hardly doubt this man is interrested in survival techniques but just saw a smart tv show. I would not apply showwrestling for fighting. I beleave its very wrong they sell the show as survivell techniques and pretends to teach when its all just for entertaiment purpose.
I know if that Bear Grylls tought the above on tv it would be like reading Scouting for boys and the vast majority of TV targeted audience would find it "boring and uncool".
I dont beleave the tehcnique is the real problem here. Tv and the people who watch it is.
