73-yr-old man shows up every week to comfort babies in ICU in US

A 73-year-old man, Dave Whitlow, shows up twice a week at the neonatal intensive care unit at a children's hospital in US to comfort babies. "Grow strong, grow smart, grow kind", he whispers to babies and also sings and plays with them while monitoring their health progress. "It's the best gig I've ever had. It just feels right," he said.
