If we are conscious of the danger of going to seed, we can resort to countervailing measures. At almost any age. You don’t need to run down like an unwound clock. And if your clock is unwound, you can wind it up again. You can stay alive in every sense of the word until you fail physically. I know some pretty successful people who feel that that just isn’t possible for them, that life has trapped them. But they don’t really know that. Life takes unexpected turns.
