ZEUXIPPUS. I have heard that Tiberius Caesar was wont to say, that he was a ridiculous man that held forth his hand to a physician after sixty. But it seems to me to be a little too severely said. But this is certain, that every man ought to have skill in his own pulse, for it is very different in every man; neither ought he to be ignorant of the temper of his own body, as to heat and cold, or what things do him good, and what hurt. For he has no sense, and is both a blind and lame inhabitant of his body, that must learn these things from another, and must ask his physicians whether it is better with him in winter or summer; or whether moist or dry things agree best with him, or whether his pulse be frequent or slow. For it is necessary and easy to know such things by custom and experience. It is convenient to understand more what meats and drinks are wholesome than what are pleasant, and to have more skill in what is good for the stomach than in what seems good to the mouth, and in those things that are easy of digestion than in those that gratify our palate. For it is no less scandalous to ask a physician what is easy and what is hard of digestion, and what will agree with your stomach and what not, than it is to ask what is sweet, and what bitter, and what sour. They nowadays correct their cooks, being able well enough to tell what is too sweet, too salt, or too sour, but themselves do not know what will be light or easy of digestion, and agreeable to them. Therefore in the seasoning of broth they seldom err, but they do so scurvily pickle themselves every day as to afford work enough for the physician. For that pottage is not accounted best that is the sweetest, but they mingle bitter and sweet together. But they force the body to partake of many, and those cloying pleasures, either not knowing, or not remembering, that to things that are good and wholesome nature adds a pleasure unmingled with any regret or repentance afterward. We ought also to know what things are cognate and convenient to our bodies, and be able to direct a proper diet to any one upon any change of weather or other circumstance.
