In a personal reflection about  universal human common points, I found a dominant subject  nowadays. How emotions, feelings are closely related to skin.  How skin remains a  taboo, why ? And why our generation is slowly forgetting about some of these thanks to internet. Based on a dialogue with a neurologist, a psychologist and a philosopher, this is the very first version of my researches, combining sensitive testimonies, intimate extract from  private diaries, science and poetry.
