What if?

What if? What if the 2012 predictions are true. What if? I do not care if any one or all of them come true, but the world does have some sort of meltdown and caves in on itself, or a large sum of the population does become nonexistant. Given you survive any sort of hypothetical situation, how would you plan to live your life and conduct yourself afterwards?

I plan to be with my family for the entire week before the whole '2012' incident just in case some nut job wants to launch a nuclear weapon somewhere in the world to try and cause a 'ripple-effect' armageddon. I feel I might as well be with them just in case something near that timeframe does happen. In wake of the '2012' movie coming to theaters soon so I figured I would ask.
