If world has ended how could i survive on something that ended? Then again the end of the world is supposed to come in December, so if i survived it's probably already 2013. It's most likely cold, since everyone died the power plants ain't working, so i just go to nearest groceries, take a bottle of finest whiskey, start a fireplace, grab a guitar, play some blues songs finishing with Arthur's Lee - Everybody's gotta live and everybody's gonna die, get drunk and then die from cold.
Sounds like a fine plan.
