An elderly couple from Iowa has taken the Internet by storm after an impromptu performance at the Mayo Clinic. Hear what Mayo doctors say is that couple's key to health. Their random act at Mayo Clinic hit Youtube and made more than six million people smile. And that's what Francis and Marlow Cowan say is what keeps them young.
"Thank you ladies and gentlemen. You know it's great to be here. We're lucky to be any place at our age," jokes Francis Cowan. "What we're going to do here for a little while is have a little fun with music."
