A groundbreaking guide to functional ageing - extending our healthy and active lives longer than ever thought possible.

Practical immortality may be within our grasp, due to cutting-edge scientific research and amazing medical breakthroughs that are coming at an astonishing speed. In Chasing Life, prominent neurosurgeon and CNN chief medical correspondent Dr Sanjay Gupta blends accounts of discoveries from around the world with advice for optimal health and longevity.

For centuries, adventurers and scientists have believed that not only could we delay death but that 'practical immortality' was within our reach. Today, many well-respected researchers would be inclined to agree. In a book that is not about anti-ageing, but about functional ageing - extending your healthy, active life - Dr Sanjay Gupta brings together compelling stories of the most up-to-date scientific breakthroughs from around the world, with cutting-edge research and advice on achieving practical immortality in this lifetime.

Gupta's advice is often counterintuitive: longevity is not about eating well, but about eating less; nutritional supplements are a waste of your money, and eating chocolate and drinking coffee can make you healthier. Chasing Life tells the stories behind the breakthroughs while also revealing the practical steps listeners can take to help extend youth and life far longer than ever thought possible.
