Humans are subject to 'malfunctions' anywhere and anytime--no different than animals, computers, cars, machinery, nature etc...Things fail or go wrong all the time and unless one is clairvoyant, the location of the 'malfunction' cannot be presupposed. Once you realize or, more importantly, accept this fact you will understand the importance of always being prepared IMO. Respectfully speaking, it sounds as though you have yet to arrive at this conclusion (hence the ambivalence).
