Many of us dream of staying as young as possible as long as possible whether we're in our 30s, 40s, 70s or even 80s, and there's a growing Conga line of products and people offering you just that dream. The dilemma is, which of the pills, mental and physical exercise programs, diets and superfoods actually work? Some of them do help to keep us young, healthy and living longer, others may work when the researchers get the potions right and some are a downright waste of money. So how do you know what and who to trust? Deeply researched and written with his trademark wit, common sense and accessibility, Norman brings together what's known, not known, hopeful but not harmful and harmful and not hopeful, summarised with quick takeaway messages backed up by the science and evidence. No matter what your age, So You Want to Live Younger Longer? gives you the information you need to make your own choices without wasting your time and money or even missing a nice dinner because you might be on a diet that is getting you nowhere. Norman disentangles our 'Book of Life' - the genes we're born with and what we subject them to later on - and shows that in the search for youth, genes matter much less than you'd think for most of us. In other words, we can overwrite our personal Book of Life and Norman's book will help you do it.
