Great link Greenhorn.
I don't believe the world will end. It is a calender - we get a new one when this one runs out lol. We do seem to be going through a period of upheaval & change, but that doesn't mean the world will end.
That there are alot of people out there who do believe it & what they might do in the days leading up to this supposed "end of world" deadline is more worrying. People do stupid & dangerous things when they panic; so I'm more concerned about crime during this period if a bunch of idiots decide to go on a rampage because they believe the world will end thus giving them free license to whatever they want.
It is interesting all the theories though
