Our society worships at the fountain of youth. Each year, we try to delay the arrival of old age, using everything at our disposal, from extreme exercise and botox to pilates and cosmetic dentistry. But in the process, are we missing out on a distinct and extraordinarily valuable stage of life? Asking whether it is better to be forever young or to grin toothlessly and live an authentic old age, bestselling author Daniel Klein journeys to the Greek island of Hydra. There he draws on the lives of octogenarian Greek locals, as well as philosophers ranging from Epicurus to Sartre, to discover the secrets of ageing happily.
