IN PICTURES: This 117 year-old woman who plays guitar, loves pets, may be the world's oldest person

In this Aug. 23, 2018 photo, great-grandniece Rosa Lucas helps her 117-year-old aunt Julia Flores Colque go for a walk outside her home in Sacaba, Bolivia. The Sacaba mayor's office has named Flores Colque a living heritage. The office and a private foundation have improved her home, building the brick path where she walks, and a shower and toilet with a railing so the centenarian can safely make her way to the bathroom at night.

Her national identity card says Flores Colque was born on Oct. 26, 1900 in a mining camp in the Bolivian mountains. At 117 and just over 10 months, she would be the oldest woman in the Andean nation and perhaps the oldest living person in the world. (AP Photo/Juan Karita)
