Stop being pussies, who gives a fuck if the world ends in 2012? Live it up rather than sit around pissing your pants worrying about it.
And just to let you know prophecies are some bullshit if you read them you should be able to tell that each of them are such big generalizations that it wouldn't be too far fetched to connect multiple ideas and meanings to them. Not one prophecy has ever specifically mentioned the exact events that occur that cause the outcome it predicts and by not giving specific dates it could also be applied to whatever historical period people want it to apply to.
So like it said stop fucking worrying and just live life the way you want to, making sure that it ends just perfect, make sure you get everything you wanted done, that way you will preoccupied doing fun shit instead of hiding in a damn bunker like a maniac.
