Healthy to 100

Brought to you by Penguin.

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.
