_ ***SHORTLISTED FOR THE ROYAL SOCIETY SCIENCE BOOK PRIZE 2022*** Did you know that we can lead longer and healthier lives by making simple changes right now? Professor Rose Anne Kenny has 35 years of experience at the forefront of ageing medicine. In Age Proof, she draws on her own pioneering research and the latest evidence to demystify why we age and shows us that 80% of our ageing biology is within our control: we can not only live longer lives but become happier and healthier deep into our later years. Effortlessly distilling scientific theory into practical advice that we can apply to our everyday lives, Professor Kenny examines the impact that food, genetics, friendships, purpose, sex, exercise and laughter have on how our cells age. This illuminating book will show you the steps you can take to stay younger for longer - and will prove that you really are just as young as you feel.
