The medical model that informs the training of doctors and the care of patients considers people to be machines with organs, limbs, and chemical processes. Wikipedia, for example, says that health is “the level of functional and metabolic efficiency of a living organism.” In plain language, health is the extent to which our limbs and organs work well, and the degree to which we are able to properly digest our food. Medical examinations are surveys of the chemical and mechanical systems of our bodies. We are mechanical patients.
