18 If you are seated among many persons, do not help yourself before they do. 19 How ample a little is for a well-disciplined person! He does not breathe heavily when in bed. 20 Healthy sleep depends on moderate eating; he rises early, and feels fit. The distress of sleeplessness and of nausea and colic are with the glutton. 21 If you are overstuffed with food, get up to vomit, and you will have relief. 22 Listen to me, my child, and do not disregard me, and in the end you will appreciate my words. In everything you do be moderate, and no sickness will overtake you.
Twofold the war, in the body, and in the soul: twofold the storm: twofold the diseases; not only in this respect, but because they are both incurable, and bring with them great calamities. Not so, frugality: but here is twofold health, twofold the benefits. Sleep of health, we read, is in moderate eating. For everywhere, that which keeps measure is pleasant, that which is beyond measure, ceases to please. For say now: on a little spark put a great pile of fagots, and you will no longer see the fire shining, but much disagreeable smoke. On a very strong and large man lay a burden which exceeds his strength, and you will see him with his burden lying prostrate on the ground. Embark too large a freight in your vessel, and you have ensured a grievous shipwreck.
