I figure if the world ends I won't be around the next day to worry about it...So why worry? 
Would not be bad if it could happen in an instant for you but............ the world does not end in 2012.
The Mayan calendar repeats itself every 5126 years.
2012 marks the end of it's 5th and final cycle which takes 25,630 years to complete.
The Mayan's 2012's end date corresponds exactly at the time of our passing through the Galactic equator. From there the calendar starts all over again.
Passing through the Galactic equator could result in a devastating cataclysmic events if in fact the do poles shift. If not, we are all safe..but according to history thats highly doubtful. Supposedly this happens every 25630 years and at that time a new ice age begins.
Imagine what would happen if all industrial transportation stopped at one time due to these events. Volcanic eruptions, earthquakes, tidal waves and tsunami's. The loss of power grids and gas lines mostly all gone. How many weeks could you live in a major city? How many months in a small town thats near a big city? How many months out in the middle of nowhere with ash and hail dumping on you if your in the wrong location? Somewhere high, away from the ocean and any nuclear plants but close to the new equator is where you want to be...and even then survival will not be easy.
If and when it should happen, people will still survive. It's just our nature. In fact,......... it's the nature of all things.
