To conclude. No man can by care-taking (as the Scripture saith) “add a cubit to his stature,”[351] in this little model of a man’s body; but in the great frame of kingdoms and commonwealths, it is in the power of princes, or estates, to add amplitude and greatness to their kingdom; for, by introducing such ordinances, constitutions, and customs, as we have now touched, they may sow greatness to their posterity and succession: but these things are commonly not observed, but left to take their chance. XXX.—OF REGIMEN OF HEALTH. There is a wisdom in this beyond the rules of physic. A man’s own observation, what he finds good of, and what he finds hurt of, is the best physic to preserve health; but it is a safer conclusion to say, “This agreeth not well with me, therefore I will not continue it;” than this, “I find no offence of this, therefore I may use it;” for strength of nature in youth passeth over many excesses which are owing[352] a man till his age. Discern of the coming on of years, and think not to do the same things still; for age will not be defied. Beware of sudden change in any great point of diet, and, if necessity enforce it, fit the rest to it; for it is a secret both in nature and state, that it is safer to change many things than one. Examine thy customs of diet, sleep, exercise, apparel, and the like; and try, in any thing thou shalt judge hurtful, to discontinue it by little and little; but so, as if thou dost find any inconvenience by the change, thou come back to it again; for it is hard to distinguish that which is generally held good and wholesome, from that which is good particularly,[353] and fit for thine own body. To be free-minded and cheerfully disposed at hours of meat, and of sleep, and of exercise, is one of the best precepts of long lasting. As for the passions and studies of the mind, avoid envy, anxious fears, anger fretting inwards, subtle and knotty inquisitions, joys, and exhilarations in excess, sadness not communicated. Entertain hopes, mirth rather than joy, variety of delights, rather than surfeit of them; wonder and admiration, and therefore novelties; studies that fill the mind with splendid and illustrious objects, as histories, fables, and contemplations of nature. If you fly physic in health altogether, it will be too strange for your body when you shall need it; if you make it too familiar, it will work no extraordinary effect when sickness cometh. I commend rather some diet, for certain seasons, than frequent use of physic, except it be grown into a custom; for those diets alter the body more, and trouble it less. Despise no new accident[354] in your body, but ask opinion[355] of it. In sickness, respect health principally; and in health, action; for those that put their bodies to endure in health, may, in most sicknesses which are not very sharp, be cured only with diet and tendering. Celsus could never have spoken it as a physician, had he not been a wise man withal,
