What do science and literature have to do with each other ? Everything and nothing at the same time. Nothing, because they are a priori two opposite fields ; everything, because there are interactions that only my dual experience as a doctor and an author can bring to light. Indeed, when you read, you realize that medicine has become a literary theme, and when you write, a whole range of hormones are set in motion. The idea of this article is to show the meaning that the author gives to today's medicine, and to put into words the hormonal processes at work through unpublished writings.
