A remarkable phenomenon of the beginning of the 21st century: an enormous number of elderly people have health metrics and functional capabilities at a level typical of people far younger. This important fact was noted in a serious 300-page report by the World Health Organization (WHO) titled “Ageing and Health,” published in 2016. At the same time, in Russia it’s becoming increasingly common to see still-not-old citizens in very poor condition—illnesses overwhelm them both at 40 and at 50. Why? How can you change your life to match the global trend—to live longer and better? That’s what Valery Novoselov’s new book is about.
