The fear of catching a disease is also a cause of illness. There are people who wonder if they are ill, and try to find out if there is something wrong with them. There are some who enjoy self-pity or the sympathy of others; these invite disease. Some entertain disease when they are to a certain extent unwell. They wish to be treated like a patient, or try to take to a lazy life. By so doing, the mind naturally holds the disease longer, since it is allowed to do so.
