Well, at last count there are over 7 billion people on planet Earth, so you don't need to be an expert in statistics to know that when December 21st? 22nd? of 2012 rolls around, the world is indeed going to end for AT LEAST 13 of them.
not this year. we will not know when it ends. besides why are people so worried about when the world will end instead of enjoying the time you have on this earth.. live life to the fullest so when our time does come we wont have any regrets
