This is one of my favourite poems and the first four lines are about my husband, I hasten to say he is not decrepit so the rest of the poem does not apply to him.
Shall I compare you to a Summers Day, Old Man
Mindful as the bright summer sky
Clear and insightful seeing all around
As only you can.
Body that creaks like blossom burdened trees
Bowed and bent and want to trembling in the breeze.
Voice croaking like the crows that settle in rows
Pecking and slicing at those below.
And as the evening light falls
You disperse with the wind
Drifting like smoke
No longer able to be
Awoke.
