The worlds' happiest Nations....!!

Adrian White, from the University of Leicester’s School of Psychology, analysed previously published data to create a global projection of subjective well-being: the first world map of happiness. The research is based on the findings of over 100 different studies around the world, which questioned 80,000 people worldwide.
The top 10 "happiest" countries:
1. Denmark
2. Switzerland
3. Austria
4. Iceland
5. The Bahamas
6. Finland
7. Sweden
8. Bhutan
9. Brunei
10. Canada

Denmark ended up at the top due to "its wealth, natural beauty, small size, quality education, and good health care".
At the bottom were the Democratic Republic of Congo, Zimbabwe and Burundi.

Does anyone ever questioned if wealth, natural beauty, small size, quality education, and good health care really make a nations inhabitants happy?
