“Death is not an evil, because it frees us from all evils, and while it takes away good things, it takes away also the desire for them. Old age is the supreme evil, because it deprives us of all pleasures, leaving us only the appetite for them, and it brings with it all sufferings. Nevertheless, we fear death, and we desire old age.” — Giacomo Leopardi, Pensieri (Thoughts)

Leopardi wrote this in his latter years, with understanding of the sufferings of old age. As his work goes, Pensieri was published unfinished. We all leave something unfinished when we leave this life. If our legacy is what we leave behind us, our unfulfilled potential is all that we never got around to. Thoreau’s “quiet desperation” is knowing the gap exists between the two.

I’m one of those people who say to the world that I will live to be 100. I know the statement is foolhardy, brash and unrealistic. It’s said tongue-in-cheek, like many things I say. We simply don’t know when our expiration date is. Given the rate of decline in our latter years that I’ve observed in the generations ahead of mine, I aspire only for good health and sound mind for as long as possible, that I may kick the sufferings of old age down the curb right to the end of this joyride.

Each day we wrestle with fear and desire. The trick to aging gracefully is to focus on filling those gaps in our potential with applied experience. We produce and share and move on to the next stage of our lives to the end of our days. If our health span allows, we may expand our legacy. So above all else, it seems, focus on increasing that health span. Fitness and mental acuity are far better desires than simply growing old.
