I do not believe the world is coming to an end next month (December 2012) with the forthcoming end to the Mayan Calendar. I found the video below (that was put out to capitalize on the hype), however, to be such a wonderful reminder of how everything will pass.
Whether life on Earth ends with a bang, or ends slowly over the course of another billion years, everything we see today is temporary.
You. Me. Our parents. Our friends. Our children (if we're lucky enough to have them). And our grandchildren. We're all temporary.
Everything passes. It would be disingenuous and tiring to think otherwise.
