It looks like a combination of the Hoarding shows meets the My Strange Addiction shows. But I'm all for preparedness when it come to the Apocalypse. Personally I haven't taken it this far, but the four couples featured on TLC's new show: Livin for the Apocalypse, are taking every precaution to ensure their families survive for as long as is possible, depending on the form in which the end of the world occurs.
If we go out with a bang, and a comet hits us, none of us has much of a chance. But if it's something like global warming (climate change) then stocking up seems like a decent idea. If we go out in a nuclear winter, pick up The Judas Syndrome series of Apocalyptic fiction and take from it what you can to either be at ground zero when the explosions go off, or stock up for a long and desperate life of nightmarish events.
