How the Finnish are world happiest [23 sec video]

"When you walk on the streets in Finland, people don't seem to be particularly happy, and I would actually think that might contribute positively to our sense of satisfaction... if you live among people where everyone's kind of like advertising their own happiness, like telling 'hey, look at me how happy I am' that might actually make you like more sad." - Frank Martela PhD Psychology, Aalto University
