In this book we can learn about medicine in a literary way. We will read about our body as a city that does everything in its power to maintain order, to keep us safe. We will learn about the medical specialties and the heroes who practice them, knowing the enormous humanity that is needed to practice that profession. We will live in the flesh how sick people feel, what illnesses are like and what it feels like to suffer the most difficult situations that human beings experience in a hospital.
