Health is the thing that makes you feel that now is the best time of the year.

The line treats “health” not merely as the absence of illness but as a lens that makes the present moment feel optimal. When you feel well, ordinary time—whatever the weather or calendar—seems like “the best time of the year.” The humor lies in its gentle reversal of seasonal nostalgia: instead of waiting for summer, holidays, or some ideal future, Adams suggests that physical vitality makes any season feel like the right one. Implicitly, the quote also critiques how sickness or fatigue can shrink the world, making even objectively pleasant times feel bleak. It’s an epigram about gratitude grounded in the body.
