" The Englishman said that he, when captured, had made and kept the following vows to himself: To brush his teeth twice a day, to shave once a day, to wash his face and hands before every meal and after going to the latrine, to polish his shoes once a day, to exercise for at least a half an hour each morning and then move his bowels, and to look into a mirror frequently, frankly evaluating his appearance, particularly with respect to his posture. "
