The need to argue that you have a disease is the biggest disease of all. When modern conditions make people ask to have a disease, these conditions are debilitating. The idea of disease is critical as ideology is reaching the point of absolute zero. The modern idea of sickness arose with modern science. This model fits well within modern mythology of science and progress.
Doctors are a new priesthood who treat the helpless, innocent victims of disease.
The upright Christians of the bible prayed for death to prevent further temptation and assure their place in heaven. Their angry God usually did not grant this death. Our secular authorities now teach us to desperately hope for ways to escape responsibility for our actions. Sickness is the escape the modern moralist teaches us to hope for. From the time that we are school kids on up, we are taught to look forward to brief periods of illness.
