Do you have any idea how many times the end of the world has been predicted?
ok, well, neither do I but it's bloody loads. 
end of the world - sky falling on our heads - gods going to smite us ...
Always been a human fear.
One day, I have no doubt, the world will end.
Either it will end for us as we will pollute it to the point that we render it uninhabitable, or we as a species will end, as most do eventually!
Or a great big meteor will smack right into the planet
or the sun will eventually die
Nothing lasts forever.
But - and here's the thing - whether the world ends in 2012, or a huge lump of rock knocks it in two
in a thousand years - there is nothing we can do about it.
Best to just live, enjoy and accept that when our time is up, it's up and no amount of worrying, stressing or running around flapping our arms in the air is going to make the slightest bit of difference
