What a Difference then between a sober and an intemperate Life? the one shortens and the other prolongs our Days, and makes us enjoy a perfect Health, and with _Juvenal_, _Mens sana in Corpore sano_. I cannot understand how it comes to pass, that so many People, otherwise prudent and rational, cannot resolve upon laying a Restraint upon their insatiable Appetites at fifty or sixty Years of Age, or at least when they begin to feel the Infirmities of old Age coming upon them they might rid themselves of them by a strict Diet and a due Regimen. I do not wonder so much that young People are so hardly brought to such a Resolution; they are not capable enough of reflecting; and their Judgment is not solid enough to resist the Charms of Sense: But at Fifty a Man ought to be govern'd by his Reason, which would convince us if we would hearken to it, that to gratify all our Appetites without any Rule or Measure, is the Way to become infirm and die young. Nor does the Pleasure of Taste last long, it hardly begins but 'tis gone and past; the more one eats, the more one may, and the Distempers which it brings along with it, last us to our Graves. Now should not a sober Man be very well satisfied when he is at Table, upon the Assurance, that as often as he rises from it, what he eats will do him no harm: Who then would not perfectly enjoy the Pleasures of this mortal Life so perfectly? Who will not court and win Sobriety, which is so grateful to God, as being the Guardian to Virtue, and irreconcileable Enemy to Vice. Surely the Example of this wise and good Man deserves our Imitation, that since old Age may be made so useful and pleasant to Men, I should have fail'd in Point of Charity to inform Mankind by what Methods they might prolong their Days. A great Assistant to that of Sobriety, and which is highly conducive to the Preservation of the whole Man, is to renew with us that habitual and beneficial Custom of the Antients in promoting _Exercise_, as one great Instrument to the Conservation of Health, and which no one can deny who has given himself the Experience of a Trial. That it promotes the Digestion, raises the Spirits, refreshes the Mind, and that it strengthens and relieves the whole Man, is scarce disputed by any; but that it should prove curative in some particular Distempers, and that too when scarce any thing else will prevail, seems to obtain little Credit with most People, who though they will give the Physician the hearing when he recommends the Use of Rideing, or any other Sort of Exercise, yet at the Bottom, look upon it as a forlorn Method, and rather the Effects of his Inability to relieve them, than a Belief that there is any great Matter in what he advises: Thus by a negligent Diffidence they deceive themselves and let slip the golden Opportunities of recovering by a diligent Struggle what could not be cur'd by the Use of Medicine alone.
