Privacy is an important aspect of the doctor patient relationship. However, too much privacy is not necessarily a good thing. Sometimes patients have serious conditions that require long treatments and doctors might not be able to continuously check if patients are adhering to dietary restrictions or physical exercise programs or medical prescriptions. Forms of intervention based on having friends and relatives participate in treatment programs are not very developed or popular because of privacy problems. However, we are all strongly influenced by what people think about us and our various behaviors, besides being ‘contagious’ change when made visible. Who is around when a patient has to decide what to eat or whether to watch TV or go for a walk? The doctor or wife/husband/friends? One smokes if one’s friends smoke, one stops if the others stop, we eat the right food if the others are also doing so and we put on weight if that is what everybody is doing. And yet most forms of health intervention are designed for single people. The force of the social relationships is not exploited the way it should be and we need to develop mechanisms that give our social contacts a bigger say in how we receive treatment and follow medical advice. Furthermore, this kind of intervention comes free of charge. Taking a prescribed medicine is not our private business like brushing our teeth and if we do it in public others notice. If we lose weight and we do so with others we check each other. If we can eat, go on holiday and play sports with our friends why can’t we take our medicines and follow our diets with them?
