“The single most powerful item in our preventive tool kit is exercise, which has a two-pronged impact on Alzheimer’s disease risk: it helps maintain glucose homeostasis, and it improves the health of our vasculature.”
The book focuses not only on lifespan but also on health span. With the aim not only to increase your lifespan but also increase the longer health span during your lifespan. Peter started off as an engineer and then went into medicine and became cancer surgeon. He then went into business and return to medicine to focus exclusively on preventative medicine. The five fundamentals which form the Palace of longer and happier lifespan and health span are (a) exercise (by far the most important), (b) nutrition, (c) sleep, (d) mental wellbeing and (e) drugs and supplements. The book is very practical and modest and does not propose one type of diet or approach to health. But it provides guidelines on what to do that will work best for your particular body, lifestyle and make up. It has the potential to be life changing.
