How beautiful my beaten feet?

Miles and miles from gainful employment..
Miles my daughters don't walk; they're both students.
They walk across campus.
My eldest walks to McDonald's.
My baby walks to the playground.
My wife walks with a cane; she has arthritis in both knees.
My mother has rheumatoid arthritis; her shoulders hurt real bad.
She has one knee replacement.
She too walks with a cane; she needs a walker.
For them I would walk many more miles, on my beaten feet.
