When I was in Iceland I talked to a doctor over there and we were discussing the lifespan. It is actually very good despite eating a LOT of sugar and doing quite a bit of drinking. But again the lifestyle over there was for the most part very peaceful. No traffic jams except for waiting for the sheep to cross the road. Crime is almost non-existent. It is clean and no artificial chemicals added to the food to worry about. Plenty of things to get out and do.....
