It wasn't the Mayans who said the world was ending. It's was stupid pseudo-intellectuals, faux-prophets and savvy businessmen capitalizing on people's fears. The makers of SPAM and MRE's are laughing all the way to the bank

In fact, the Mayan's statment on the end of the Long Count calendar's 13th b'aktun is this:
In a statement released by Oxlaljuj Ajpop, the end of the cycle simply "means there will be big changes on the personal, family and community level, so that there is harmony and balance between mankind and nature."
Just saying... if you're gonna generalize about a people, at least have your facts straight.
