I have always remembered a comment by an Arizona sheriff from long ago - "most of the survivors he had encountered possessed strong egos." This came home to me on a particularly dicey night out when I thought my companions might have triggered a search. I was determined to look good and to be capable of offering any arriving search party a working cook stove and a steaming cup of coffee. It was important to appear to be capable and in control of the situation (which is probably one of my motivations for prepping today).

I think it comes down to personality being an important factor in a survival situation, and religious orientation, or lack thereof, may be a component of a survivor's personality.

I am not a Mormon, nor am I likely to become one, but I have always thought their practice of stocking a year's worth of food to be an excellent notion, especially in the pioneer conditions in which that idea evolved.
