London, Aug 28 (IANS): The world's oldest person - Besse Cooper - has turned 115. On the secret to her long life, she said: "I mind my own business. And I don't eat junk food."
Cooper's birthday was recently celebrated at her residence in Monroe, Georgia, The Telegraph said.
A Guinness World Records representative delivered Cooper a plaque that certifies her as the oldest person on earth.
Her son, 76-year-old Sidney Cooper said: "She still remembers things and thinks clearly and talks. But she has her good days and her bad days. I'd say she sleeps about 80 percent of the time."
Born in Tennessee in 1896, Besse Cooper moved to Georgia during World War I. She married her husband Luther in 1924, and they had four children. Today, she has 12 grandchildren and more than a dozen great-grandchildren.
