In Utopia it appears Thomas More alludes to his views on aging; specifically that it could be considered a disease. Seems like a pretty novel viewpoint for the time (16th century), I wonder if there are notable earlier mentions of similar ideas.
None are suffered to put away their wives against their wills, from any great calamity that may have fallen on their persons; for they look on it as the height of cruelty and treachery to abandon either of the married persons when they need most the tender care of their comfort, and that chiefly in the case of old age, which as it carries many diseases along with it, so it is a disease of itself.
The idea of old age as a disease has not taken on mainstream acceptance yet, and in all fairness it remains to be seen whether this is a correct frame, but the concept is quite powerful and has already captured many of today’s thinkers (especially some wealthy ones).
