A bald, overweight man might want to control the release of various parts of his electronic medical records to an ever narrowing circle of people. His baldness and his weight are obvious (if not precise), but he sees no need for knowledge of his participation in his employer’s diet and exercise program to go beyond his doctor, wife, friends and co-workers. He is willing for his doctor, wife and close friends to know about his antibalding medication, but he wants only his doctor and his wife to know about his sexual dysfunction.
