Learn the art of growing old from the supercentenarians living life to the fullest. It's said that life begins at 40—but that number is constantly revised upwards as we live longer and longer. With the number of centenarians having quadrupled in the last 30 years, more of us can now hope to reach the 100-year mark than ever before. But how can we navigate this journey with grace, dignity and style? In this charming and informative book, Daniela Mari, an Italian doctor caring for some of the oldest people on the planet, draws on her experiences as a renowned gerontologist to reveal the science behind a healthy, happy old age. It turns out that the world's centenarians can teach us a thing or two about ageing well. And the secrets are not always what you'd think. Informed by the latest medical studies and incredible stories of individual longevity, Mari shows how our lifestyles can far surpass the influence of our genetics and why a daily glass of liquor isn't the end of the world. From our sleeping habits and diet to the crucial importance of our passions and interests, this is the essential handbook for a fruitful and fulfilling old age.
