The contemporary information is often bewildering, it may seem that the lives of all people over the age of 35 are inconspicuous. How do "adults" live on? Is it true that older people are all sick, boring, outdated, do not want sex and do not like themselves in the mirror? No, it is not. It is high time to reconsider the attitude to age, growing up, aging and chronic diseases. And not just "make yourself stop getting sick", but understand what is happening to us, what are the risks and opportunities at each age, and continue to grow up rather than old. "The adult book. How to grow up, but not grow old" will help. It discusses lots of things: the factors that slow or accelerate aging, the prevention of cardiovascular diseases and cancer, living with diabetes and lung and intestinal diseases, body care from eyes to bones, mental stability, general and specific nutrition advice, menopause, erection, sex, and how to live long and happily. But without magic and magic pills.
