A woman with severe diabetes (blood sugar level <400 mg/dL) refused to control her diet. Once day, when I became angry with her, I told her she could go blind. To emphasize the difficulty she would have if that happened, I told her husband to blindfold her for two hours and not let her sit down. He was to keep her busy— ask her to bring a glass of water, get the mail, make tea, fix the bed, clean the sink. Ever since, she has been a good patient, keeping her bllod sugar in the 140-160 range.
