Happiness is that quirky, elusive emotion that the Declaration of Independence maintains we have every right to pursue. And we do pursue it: we are suckers for an endless stream of self-help books that promise a carefree existence for a mere $24.95; and television hucksters of every kind claim they have the key to Nirvana. So the happiness business, at least, is one big smiley face.
As for the rest of us, the main scientific survey of international happiness carried out by Leicester University in England ranks the U.S. a distant 23rd, well behind Canada and Costa Rica. But you'll be pleased to know we beat Iraq and Pakistan.
