Interesting, quick breakdown of survival school philosophies. That bolded sentence about survival skills not being difficult but rarely practiced enough is certainly a key point. Actually, sounds like almost everything new I've had to do for work, too!
Actually, the sentence before, about how a survival situation can either be a challenge or a terrifying, overwhelming ordeal is true of so many unexpected situations. For example, I'm a sunny California boy, have never driven in the snow, and would probably be absolutely freaked out if I started skidding on the ice even at a relatively slow speed, while someone who grew up in this stuff could calmly deal with it.
