For decades, the medical community has looked to a variety of reasons for why we age, and the consensus is that no one dies of old age; they die of age-related diseases. That's because ageing is not a disease – it is inevitable.

But what if everything you think you know about ageing is wrong?

What if ageing is a disease? And that disease is curable.

In Lifespan, Dr David A. Sinclair, one of the world’s foremost authorities on genetics and ageing, argues just that. He has dedicated his life’s work to chasing more than a longer lifespan – he wants to enable people to live longer, healthier, and disease-free well into our hundreds. In this book, he reveals a bold new theory of ageing, one that pinpoints a root cause of ageing that lies in an ancient genetic survival circuit. This genetic trick – a circuit designed to halt reproduction in order to repair damage to the genome – has enabled earth’s early microcosms to survive and evolve into more advanced organisms. But this same survival circuit is the reason we age: as genetic damage accumulates over our lifespans from UV rays, environmental toxins, and unhealthy diets, our genome is overwhelmed, causing gray hair, wrinkles, achy joints, heart issues, dementia, and, ultimately, death.

But genes aren’t our destiny; we have more control over them than we’ve been taught to believe. We can’t change our DNA, but we can harness the power of the epigenome to realise the true potential of our genes. Drawing on his cutting-edge findings at the forefront of medical research, Dr Sinclair will provide a scientifically proven roadmap to reverse the genetic clock by activating our vitality genes, so we can live younger for longer. Readers will discover how a few simple lifestyle changes – like intermittent fasting, avoiding too much animal protein, limiting sugar, avoiding x-rays, exercising with the right intensity, and even trying cold therapy – can activate our vitality genes. Dr Sinclair ends the book with a look to the near future, exploring what the world might look like – and what will need to change – when we are all living well to 120 or more.

Dr Sinclair takes what we have long accepted as the limits of human potential and mortality and turns them into choices.
