Apparently, the world was to end on 21 December 2012 (according to some fringe interpretations of the Mayan calendar). Of course, in actual fact, at each moment, there is always the possibility — however small — that the world could end. A meteor could come out of the sky this very second and obliterate everything. We also live with the possibility — far more probable than the end of the world — that our mortal existence could cease at any moment. So whether it is the end of our life, or of the world, the end is our constant companion.
