Not gonna lie either, it's something I have thought about too. But when ya start to think about it, there have been so many "end of the world" dates set and all have gone by with nothing happening. And I know disasters seem more common, but that's because we are more conscious of them (news is instant these days)
Also, many scientists believe that the 2012 date is actually inaccurate and that it may even have occurred! And also, many scholars believe that the 2012 date is not a "end of the world" scenario, but more of a world wide "realization" kinda deal.
