I'm inclined to stop reading after the phrase "United Nations Annual Report On Happiness."
It's really just a report on which countries adhere most strictly to the United Nation's idea of what a "happy" country should look like. Not an objective measure of how happy the people in those countries actually are.
For example, Scandinavian countries frequently score highly on those lists, but they also have some of the highest rates of antidepressant use in the Western hemisphere.
And while this isn't exactly scientific, I've known a lot of Norwegians. There are quite a few of them in Newcastle and I had Norwegian friends back when I lived there. While I wouldn't exactly call them "depressed," I wouldn't call them happy either. They were all extremely cynical, had a very dark/bleak sense of humor and drank like fish. Hey wait a minute though.....maybe they're onto something there.....
It reminds me of an article I read in the Guardian a few years ago about the
myth of Scandinavian happiness. It describes Norwegians as "insular and xenophobic," qualities I'm not sure the UN would be happy about adding to their "happiness" metric.
