The next generation of nurses are deeply not interested in the geriatrics and it could be because of the emotional shock of their first experiment during their training period, when they had to wash an elderly. The subject is trying to understand the social links and the human relationships in the social group of the team and also trying to understand the interaction between someone who doesn't know a lot and someone who is well-informed. The body is then the « subject » of mediation. This experiment is compulsory and it can't be avoided, isn't it a way of building the identity of the next nurses ? What meaning can we give to the care and the take care when the interaction with « the other » is so violent? This test, based on the hygiene and the comfort care, isn't it a sensitive and poly-sensorial experiment in an initiatory ritual ?
