Jack Prince, a 93-year-old World War II veteran, says the secret to his longevity is his love of the piano and desire to constantly improve his playing.
"I think it's very useful for somebody my age to have something that you have to work at, and I do work," he told Good Morning America. Every two weeks, Prince takes private lessons at the Wisconsin Conservatory of Music, and he practices five or six days a week, an hour every time. He's not just practicing for fun — he's also getting ready for a milestone. "I love to perform, and so with a birthday coming up, I'm preparing for my 94th birthday recital," he said.
