On the Japanese island of Okinawa, in the mountains of Sardinia, on the Greek island of Ikaria: in a few places around the world, strikingly many people grow very old – often past a hundred, and remarkably healthy. Researchers call them "blue zones".

The intriguing part: these regions are far apart and have very different cultures – and yet they share some habits.

People there mostly eat simply and largely plant-based, with plenty of vegetables and legumes and little meat. They move a lot in everyday life without going to the gym – they walk, they work in the garden. They are firmly embedded in family and community and often have a task, a sense of purpose, well into old age.

No single "miracle cure" explains the long life – it is the interplay. Genetics plays a role, but lifestyle and environment matter at least as much.

The takeaway: the ingredients for a long life are unspectacular and within reach for many – mindful eating, movement in everyday life, real relationships and the feeling of being needed.
