In 2020, over 100 million EU citizens were aged 65 or older, comprising a fifth of the total global population of centenarians. By 2050, this demographic will swell to almost onethird of the population.The prevailing notion of longevity, tied to the traditional retirement, suggests that life after sixty is a time of gradual social disengagement specially from productive contribution to society. This book advocates a fresh perspective, recognizing that life expectancy is hitting new highs and necessitating a re-evaluation of longevity. European, Japanese, and North American countries particularly feel the urgency to collaboratively shape a new vision for extending longevity.
