For what wears out the life of mortal men?
'Tis that from change to change their being rolls:
'Tis that repeated shocks, again, again,
Exhaust the energy of the strongest souls,
And numb the elastic powers.
Till having us'd our nerves with bliss and teen,
And tir'd upon a thousand schemes our wit,
To the just-pausing Genius we remit
Our worn out life, and are — what we have been.
