I subscribe to that idea.
There are a lot of doom and gloomers about Dec 21, 2012. That's the date of the Winter Solstice and the end of the Mayan sacred cycle of 1,872,000 days. This cycle began on the Winter Solstice in 3114 BC. A lot of people are loosing bladder control over this facet of Mayan astronomy, but I say; "heck: its just like an odometer change." the Mayans were into really big, big numbers. Dec 22, 2012 begins the start of the next Mayan sacred cycle, which will last for 1,872,000 days.
But then again, we'll all be hit by the Asteroid 1950 DA in March 2800 and there will be no space aliens to rescue us (as we're not interesting enough). So that will be it.
