"Mayo Clinic badly botched Hemingway's treatment when he was admitted for depression and given two disastrous series of electroshock therapy in 1960—61, He had been frightened and depressed when told by a Cuban doctor in the summer of 1960 that he had hemochromatosis, a rare, chronic, and fatal form of diabetes "that makes you go blind and permanently impotent." The Mayo doctors also suspected that he had this disease, but they did not attempt to relieve his anxiety by doing a biopsy and making a definite diagnosis."
