“If that had not been the case, we should have had in him a second brilliant light in the political horizon; for he had added a wider cultivation to his father's greatness of spirit. What wonder, then, that old men are eventually feeble, when even young men cannot escape it? My dear Laelius and Scipio, we must stand up against old age and make up for its drawbacks by taking pains. We must fight it as we should an illness. We must look after our health, use moderate exercise, take just enough food and drink to recruit, but not to overload, our strength. Nor is it the body alone that must be supported, but the intellect and soul much more.
For they are like lamps: unless you feed them with oil, they too go out from old age. Again, the body is apt to get gross from exercise; but the intellect becomes nimbler by exercising itself. For what Caecilius means by "old dotards of the comic stage" are the credulous, the forgetful, and the slipshod.”
