Younger for Longer shares the author's detailed knowledge of hormones, toxins, nutrition, stress and other factors to provide a comprehensive, up-to-date and medically rigorous description of health, ageing and the human body. He reveals practical steps to slow the ageing process - in short, how to stay younger for longer.

The goal of this book is to show readers how to live a healthy life free from the debilitations of ageing, helping them to stay mentally alert and physically active, and making sure they get the most out of all of their years.

That means aiming for optimal health. However, focusing on one factor alone will not get them there. Our sleep, our mood, what we eat, our detoxification system and our hormones are just some of the factors that interact in amazing ways to make us who we are; they are also at the very heart of the aging process.

This book shows how these different strands combine in ways that can be positive or negative - and explains why this interaction depends far more on the lifestyle we choose than on the genes we inherit. In that way it gives the reader a unique and comprehensive understanding of their body and tells them how, with this knowledge, they can maximize their health.

The topics range from nutrition, toxins, men's health and women's health to understanding why our skin, brain and liver age - and how to undo the damage and stave off ageing. But the book's main focus underlying all of this is hormones: the chemicals that tell different parts of our body what to do. Our hormone levels vary throughout our life, but if they are supported correctly they can keep us youthful and vital into our final years.

Finding health, then, is not about seven ways to detox or the five best vitamins. The body is far more complex than that and, in an approach aimed specifically at the layperson, Younger for Longer traces the exciting path of how the body works to help the reader create the best person they can be for the rest of their life.
