This is the last post of 2011. I hope your 2012 will be peaceful, prosperous and joyful. And that Maya calendar that ends Dec. 21, 2012? That some have interpreted as a forecast of the end of the world? I really wouldn’t sweat it. Just think of those guys carving calendars out of stone about the 5th century BC. When they got ahead 2,500 years, it isn’t hard to imagine them saying, “Well, that ought to hold us for a while.”
