Scientists have been searching for a cure for old age for hundreds of years, but so far, it seems, they have found nothing. Does this mean he doesn't exist? Or maybe they are just looking in the wrong places? In her book, biologist and science journalist Polina Loseva acts as an advocate for modern science on aging and talks about what gerontologists are doing today and how to correctly interpret their results. Who is to blame for the fact that we are getting old? What can become our protection against old age: telomerase or antioxidants, hormones or diets? Biologists have not yet come to a single answer to these questions, and the reader, if he decides to move from reflection to action, will have to make his own choice. This book will become a guide to modern theories of aging not only for biologists, but for everyone who is interested in how help your body fight an unequal fight against time.
