Longevity: The definitive guide to a long, healthy and happy life

by Susannah Marriott

Good ageing is about being increasingly resilient to the stuff life throws at us - change, loss, adversity - so we can process it in a way that keeps life feeling meaningful and satisfying, and we remain motivated to bounce back and try new things. What makes us resilient? An active life with a good diet and enough sleep, a sense of life-satisfaction and self-esteem, positive brain stimulation, satisfying human interaction and spiritual sustenance.


The desire for a long, healthy and happy life is a universal one, yet society has a deep fear of ageing. Longevity offers an all-encompassing, holistic look at how the body ages - and what we can all do to age better.
You'll discover that a longer life blessed with health and happiness is within reach by


- How the ageing process works - and what you can do to enjoy a better quality of life.
- What history, biology, Eastern philosophy, Western science can teach us about maintaining optimal health.
- The important role that a sense of purpose, connection, love and curiosity have in helping us to live well and live happily.
