I’m growing fonder of my staff;
I’m growing dimmer in the eyes;
I’m growing fainter in my laugh;
I’m growing deeper in my sighs;
I’m growing careless of my dress;
I’m growing frugal of my gold;
I’m growing wise; I’m growing, — yes, —
I’m growing old!

John Godfrey Saxe (1816-1887) American poet and satirist

“I’m Growing Old,” st. 3
