I've become interested recently in certain "breeds" of American that we don't really have here in Europe. One of the most interesting is the Prepper, people who build shelters or bunkers and stockpile food, equipment and often weapons and ammunition in preparation for the breakdown of civilisation.
Is anyone here a Prepper? If so, what are your preparations? How do you think civilisation is most likely to break down, and how likely do you think it is to happen in your lifetime?
