He never succumbed, due to old age, to extravagance in food, nor did he change his mode of dress because of frailty of the body, nor even bathe his feet with water, and yet in every way he remained free of injury. For he possessed eyes undimmed and sound, and he saw clearly. He lost none of his teeth—they simply had been worn to the gums because of the old man’s great age. He also retained health in his feet and hands, and generally he seemed brighter and of more energetic strength than those who make use of baths and a variety of foods and clothing.

—Athanasius, The Life of Antony
