Well, it's tomorrow. The end of the world, I mean.
Of course it is easy to laugh at this, particularly since if you are wrong, there will be nobody to say 'I told you so'. Except those people in that French mountain village whom the ancient Mayans unerringly picked out for saving.
In case you are worried, the Independent newspaper publishes a critique of the doomsayers' understanding of the calendar. You may think you want to read it, but I'll just give you a taste: '21st December, 2012 is a 'round date', at least in the Long Count. We refer to it as 220.127.116.11.0. ie it is the 13 Bak'tun period ending (an amount of 13 times 144,000 days comes to pass) since the 'era day', the creation of the current world in classic Maya mythology.
The conclusion is that whilst it is the end of something, it is not the end of the world.
It's probably best just to pour yourself a stiff drink.
