Most emotional: The Philippines. Least emotional: Singapore.
Self-reporting, so I question whether they've really measured emotion. One question was: "Did you smile or laugh a lot yesterday?" Depends on the meaning of "a lot," the vividness of memories of "yesterday," whether you smile and laugh when you're feeling joyful, and so forth. But... whatever. It was nice to see a color-coded map.
It made me smile.
