Five countries where people live the longest

Nicoya, Costa Rica
The lowest rate of middle-aged mortality is on the Nicoya peninsula—which means these people have the best chance of living to a healthy age of ninety. The people of Nicoya consume what I consider to be the best diet the human species has ever had, dominated by three foods: corn tortillas, black beans, and squash, complemented with tropical fruits, year round. It’s cheap, it’s delicious, it’s high in complex carbohydrates, it has all the amino acids necessary for human sustenance, it’s sustainable for the land, and doesn’t deplete the soil or involve slaughtering animals (both are problematic for the environment).
