The ultimate guide to living a longer and healthier life from top longevity expert

A revolutionary approach to longevity and ageing

In many western countries, people complain of turning invisible after 50. When they hit their mid-60s, they expect or are forced to retire, cutting them adrift from social networks and leading to a loneliness epidemic. But it doesn’t have to be this way.

In Healthy to 100, Ken Stern uncovers the ground-breaking secrets of the winners in healthy longevity – countries like Singapore, Spain, Japan and South Korea – who are all top-rankers on the ‘Healthy Longevity Index’, the best measure not just of living long, but living long well.

Bringing together the latest science of ageing and real-life stories, this book offers us a personal and societal guide to living a fulfilling life after 65: one where purpose, learning, community and intergenerational connection are the pillars of good health. Rather than advocating for special diets or exercise regimens, Healthy to 100 offers a hopeful, attainable and research-backed model for anyone seeking a longer, healthier and purpose-driven life.

Praise for Healthy to 100

The right book at the right time. Healthy to 100 is a fascinating and hopeful voyage through five of the world’s healthiest and longest-lived countries, revealing how those societies are supporting connection, community and purpose – and healthier, longer life as a result. Ken Stern weaves together the latest research with his own keen eye for story and detail in this compelling and fun read. For anyone thinking about what the second half of life should look like, Healthy to 100 is a must-read.

Chip Conley, New York Times bestselling author of Learning to Love Midlife

Rather than learn from forty-year-old tech bros advocating unproven supplements and radical exercise programs, Ken Stern goes around the world to gather wisdom from the everyday lives of older people to find what makes for a healthy, engaged and purposeful life wherever you live. Success lies less in cracking human biology and more in cracking human connectivity. An insightful and entertaining book that is a must-read for anyone who is thinking about how to live a longer, healthier life.

Andrew Scott, co-author of The 100-Year Life

Beautifully written, filled with indelible stories, and deeply rooted in research, Stern’s book offers our best blueprint for realising the vast promise of the longevity revolution, as individuals and as societies.

Marc Freedman, author of How to Live Forever

Which country has unlocked the secret to aging well? After traveling the globe to study the world’s longest-lived populations, Ken Stern discovered something surprising: it’s not Mediterranean diets, cutting-edge healthcare, or exercise regimens that matter most. The real key to a long, vibrant life lies in our connections with one another. Healthy to 100 is both a wake-up call about our loneliness epidemic and a hopeful roadmap for building the social infrastructure we need to thrive at every stage of life. Compassionate, insightful, and surprisingly uplift ing, this book will change how you think about growing older – and inspire you to invest in what truly matters.
