With the recent exception of the prime minister resigning after his name came up in the Panama Papers, everything is right in Iceland. People eat simple – lots of seafood, dairy from grass-fed cows, and locally grown produce with no pesticides, which is what personal trainers never consume. Locals swim a lot. (You would too if you had natural hot springs nearly everywhere you turn). People use them for family fun and to relax. The nation of 320,000 people is a close-knit society. It ranked No. 3 on the most recent World Happiness Index.
