Maturity by Philip Larkin
A stationary sense... as, I suppose,
I shall have, till my single body grows
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
Of compensating act and counter-act
Defeat and counterfeit, makes up, in fact
My ablest time.
