Maturity

A stationary sense . . . as, I suppose,
I shall have, till my single body grows
        Inaccurate, tired;
Then I shall start to feel the backward pull
Take over, sickening and masterful —
        Some say, desired.

And this must be the prime of life . . . I blink,
As if at pain; for it is pain, to think
        This pantomime
Of compensating act and counter-act,
Defeat and counterfeit, makes up, in fact,
        My ablest time.
