A 100-year-old great-grandmother shows that age is nothing but a number. "The video makes me smile every time I watch it," Elisabeth Cockrell's granddaughter, Treasure Mitchell, told InsideEdition.com. Cockrell busted out her best moves to Bruno Mars' "24K Magic" during her birthday party in Marina Valley, California last weekend. A video shows her loved ones cheering her on as she grooves to the music. Her grandson posted a video of her moves to Facebook, where it's been viewed more than a million times.
