Letters 83.4

Do you ask who are my pacemakers? One is enough for me,—the slave Pharius, a pleasant fellow, as you know; but I shall exchange him for another. At my time of life I need one who is of still more tender years. Pharius, at any rate, says that he and I are at the same period of life; for we are both losing our teeth. Yet even now I can scarcely follow his pace as he runs, and within a very short time I shall not be able to follow him at all; so you see what profit we get from daily exercise. Very soon does a wide interval open between two persons who travel different ways. My slave is climbing up at the very moment when I am coming down, and you surely know how much quicker the latter is. Nay, I was wrong; for now my life is not coming down; it is falling outright.
