On the Greek island of Ikaria, people suffer 80 per cent less dementia, 50 per cent less heart disease and 20 per cent less cancer than the rest of the world. Marcus Pearce considers why. Known as “the island where people forget to die”, Ikaria first came to prominence when National Geographic journalist, Dan Beuttner and his team, discovered the island as a Blue Zone. There are five Blue Zones in the world – small pockets on earth where the population enjoys longer lifespans than the average. Okinawa, Sardinia, Nicoya in Costa Rica and Loma Linda in California all share with Ikaria this prestigious title.
