As to what pertains to age: the middle-aged sustain hunger more easily, less so young people, and least of all children and old people. The less readily one supports it, the more often should food be taken; one who is growing needs it most. Children and the old should bathe in warm water. Wine should be diluted for children; for the old men it should be rather undilute: but at neither age be of a kind to cause flatulence. It matters less for the young what they take and the way they are treated. Those who when young are relaxed, when old are generally costive; those constipated in youth are often relaxed when old. It is better to be rather relaxed when young, rather costive when old.
