This dancing great-great grandmother proves once and for all that you're only old as you feel.

You'd never guess Lillian Thomas is 93-years-old by the way she dances, dresses and takes selfies.

In addition to acting much younger than most people her age, this granny has certainly kept up with the latest trends and music, which means she's learned to embraced new things.

It's said part of the secret to a long life is to keep both physically and mentally active. It's more than obvious Thomas has figured that out. By adding a healthy dose of humor to her life, it's likely she'll still be going at 103. Go granny go!
