text: The old Romans had a custom which survived even into my lifetime. They would add to the opening words of a letter: "If you are well, it is well; I also am well." Persons like ourselves would do well to say: "If you are studying philosophy, it is well." For this is just what "being well" means. Without philosophy the mind is sickly, and the body, too, though it may be very powerful, is strong only as that of a madman or a lunatic is strong. This, then, is the sort of health you should primarily cultivate; the other kind of health comes second, and will involve little effort, if you wish to be well physically. It is indeed foolish, my dear Lucilius, and very unsuitable for a cultivated man, to work hard over developing the muscles and broadening the shoulders and strengthening the lungs. For although your heavy feeding produce good results and your sinews grow solid, you can never be a match, either in strength or in weight, for a first-class bull. Besides, by overloading the body with food you strangle the soul and render it less active. Accordingly, limit the flesh as much as possible, and allow free play to the spirit. Many inconveniences beset those who devote themselves to such pursuits. In the first place, they have their exercises, at which they must work and waste their life-force and render it less fit to bear a strain or the severer studies. Second, their keen edge is dulled by heavy eating. Besides, they must take orders from slaves of the vilest stamp, – men who alternate between the oil-flask and the flagon, whose day passes satisfactorily if they have got up a good perspiration and quaffed, to make good what they have lost in sweat, huge draughts of liquor which will sink deeper because of their fasting. Drinking and sweating, – it's the life of a dyspeptic!
