“Hold fast, then, to this sound and wholesome rule of life; that you indulge the body only so far as is needful for good health. The body should be treated more rigorously, that it may not be disobedient to the mind. Eat merely to relieve your hunger; drink merely to quench your thirst; dress merely to keep out the cold; house yourself merely as a protection against personal discomfort.”

— Seneca, Epistle VIII
