## Description

In this paradigm-shifting book from acclaimed Harvard Medical School doctor and one of TIME magazine’s 100 most influential people on earth, Dr. David Sinclair reveals that everything we think we know about ageing is wrong, and shares the surprising, scientifically-proven methods that can help readers live younger, longer. 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 THE EVOLUTION OF AGEING, Dr. David 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 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. LIFESPAN is destined to be the biggest book on genes, biology, and longevity of this decade.

Review: Important & Informative - This is a fascinating book covering the latest advances (including from his lab at the Harvard Medical School in Boston and others) in ageing research. Dr Sinclair starts by discussing our attitudes towards ageing – most people think of it as inevitable. As a result, while many serious diseases such as cancer, heart diseases, dementia and others have received considerable funding, ageing still continues to receive a small fraction of that. Also, grants awarded to ageing are often used up for research into diseases more prevalent typically in old age (such as dementia), rather than ageing itself. The fact though is that ageing leaves you more susceptible to many diseases and also invariably affects quality of life for many. The advances in medicine have improved the average age by greatly reducing early deaths and fighting diseases. Humankind has so far however not been able to raise the maximum age – very few make it past 100. Ageing need not be considered inevitable says Dr Sinclair, and should rightfully be declared a disease. There is now a reasonably good understanding of why we age. While side effects such as telomere shortening were known since some time, the underlying cause may be simpler and more focused. It is the result of the survival circuit (which all organisms have) being unable to cope with increasing damage which can no longer be repaired. Research is reaching a point where this can be arrested – in a few years. Even if medical intervention to significantly increase lifespan is years out – there is a lot we can do even today. There is evidence that intermittent fasting, exercise (such as yoga and some strenuous), a careful diet plan (lots of veggies, nuts avoiding meat, processed foods, dairy & sugar) and some already available medication (the evidence though is not fully conclusive) can do a lot to extend lifespan. He also cites his personal example and that of his father, who remains active well into his eighties. I looked at some of his photos and he certainly looks well younger than his age of 50+! The last section covers what we can expect in the future and the impact of arresting ageing on society and nations. This section is unnecessarily longer than required, and goes into some simplistic ethical discussions (as expected steering clear of the speciesism and animal cruelty rampant in medical research). This is an excellent and very readable book which I strongly recommend all read. My rating: 4.5 / 5.
Review: A must read! - A really good book about why we age, and also gives advice regarding how to stay young through dieting and exercising. The author argues that ageing is the mother of all diseases and the rest of them like cancer, diabetes, etc derive because of ageing and hence he urges to allocate more resources in solving the ageing disease rather than the branching diseases. We all thought that ageing is normal and everyone goes through it, but this book really challenges that perception.
