Jan 25 2012: This is very interesting. I'm from Japan and even though we are the 4th most peaceful country in the world, there is a statistics that we are like the 100th happiest country in the world. I wonder what it would actually look like if we do have a Smiling Indicator and make a graph out of it in comparison to the world's highest GDP countries. I bet that developed countries would actually have less smiles because of the millions of issues they are encountered. Let's face it: America is the country with the highest GDP and a pretty high income, but the problems we face: Health Care, Government, Immigration, Segregation, etc.... so I bet they won't top the Smiling indicator.
