 Is there pixie dust mixed into the food and drink of the happiest places on Earth? Or is it something in the crisp clear air of many of the world's happiest nations?

When the United Nations declared March 20 the International Day of Happiness, it recognized the relevance of "happiness and well-being as universal goals and aspirations in the lives of human beings around the world." This officially designated happy date is marking its second year.

Bet you can't watch this without smiling

The happiest of countries -- many of which are in Scandinavia according the latest World Happiness Report -- have a robust combination of higher life expectancy, gross domestic product per capita, social support, generosity, freedom to make life choices and lower perceptions of corruption. By analyzing happiness data, officials hope to improve the world's social, economic and environmental well-being.
