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 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.
