World ending

if the world is ment to end in 2012, wats the point of staying in a dead end jobs, saving up for a future that we're not gonna have? Since i heard of this, i cant stop thinking about it? Tho i am in two minds about it all, like if the earths crust is ment to get too hot and we blow up and all that jazz, but wouldnt we more than likely have already started having effects of this, i know there's been mad wether and natuaral disasters, but they have all been the oppisite of a heat reaction.... I dunno i like to think that i'd still live forever...
