Bhutan started a Gross National Happiness Index. Now, there is a United Nations World Happiness Index. In 2012, Denmark was top, Canada 5th, New Zealand 8th, US 18th, Japan 44th, and Togo was last. Why do you think Japan is so low in spite of being rich country?

I think a lot of people are rich in the world. They are happy from someone else's perspective but they aren't satisfied with their lives. I think measuring the happiness index is not relevant weather the country is rich or poor.
