FROM CNN's Jack Cafferty:
It's the end of the world as we know it - at least for one in seven people worldwide.
A new poll conducted for Reuters shows nearly 15% of people believe the world will end during their lifetime.
And 10% think the end could come as soon as this year - that's based on the end of the 5,100-year-old Mayan calendar that arrives on December 21, 2012.
Pollsters questioned more than 16,000 people in more than 20 countries. It turns out predictions of doom and gloom vary widely depending on where you live.
Only 6% of the French and 8% of the British fear Armageddon in their lifetime compared to 22% in Turkey and right here in the United States.
The Russians and the Poles were most likely to fear the end of the world as coming this year.
Experts say people under 35 and those with lower education or income are more likely to believe in an Apocalypse. Perhaps it’s because those over 35 have lived long enough not to worry about it.
Meanwhile, there have been many End of Days predictions over the years coming from the Chinese, the Egyptians, Native Americans, the Irish, etc.
But for some reason this Mayan Doomsday prediction has attracted millions, maybe even billions, of believers. Hundreds of thousands of websites have popped up devoted to the end-of-the-world fears.
However, experts - including NASA - say there's nothing to it and compare it to the Y2K scare which turned out to be much ado about nothing.
So here's the Question: What does it mean when one in seven people think the end of the world is coming?
