If the world is gonna be destroyed, what good is having a year supply of food and water etc? It would make more sense to just live life normal that way if the world doesn't end then you didnt waist your money on stuff you don't need.
I think it's only the Mayan's and the Christian's worlds that will end (I have inside information). I'm willing to watch your dogs, takes care of your plants, start your car(s) now and then so the battery won't go dead. All for a small fee. Hey you won't need your $$ anyway.
