A man can enjoy a terrestrial paradise after eighty, but it is not to be obtained, except by strict temperance in food and drink, virtues acceptable to God, and friends to reason.
Our beneficent Creator is desirous, that, as he originally favoured human nature with longevity, we should all enjoy the full advantage of his intentions, knowing, that when a man has passed seventy, he may be exempt from the sensual strivings, and govern himself entirely by the dictates of reason.
A man cannot have a better guide than himself, nor any physic better than a regular life.
