What is the Secret to a Longer Life?

Why do people who live in five communities around the world – known as Blue Zones- consistently outlive the rest of us on the planet? Professor Cregan-Reid goes in search of the secret of a long life. He visits Sardinia home to one of those long lived communities where several villages boast dozens of people aged 100 or more.

Instead we are succumbing to lifestyle diseases and longevity could even be about to fall for future generations. The good news is researchers in the Blue Zones have identified seven easily adapted rules for a longer life!
