>if things turn so badly to shit you need a year of food, food is going to be the least of your worries.
I don't see why this is the case -- saying "doing X is going to be the least of your worries" seems to imply that there are going to be other priorities and "X" will be ignored -- i.e. "charging your phone is going to be the least of your worries." But food... you _need_ food, even if there are other crazy things happening all around you. If that's the case, I can't help thinking it would be better to do the things you CAN do to prepare. One less thing, etc.
