In this episode you will discover precautions that are within everyone's reach but which some populations or groups have always practiced with extraordinary results. The same behaviors that have recently attracted the attention of doctors and researchers who study the mechanisms of aging. We will talk about nutrition, we will try to understand which type of movement is best suited to keeping us fit over the long distance and much more. The journey will start from the islands of Okinawa, Japan; we will discover how well-being arrived on these islands just a few decades ago and those who are now elderly have led a spartan existence for a good part of their lives, often marked by periods of enormous difficulty. Yet, those very elderly people seem to have slowed down the effects of old age. In these islands people live for a long time, but above all the diseases typical of old age are rarer.
