Celebrity 127-Year-Old Woman Says She's the World's Oldest Living Person Leandra Becerra Lumbreras celebrated her history-making birthday Sunday By Michele Corriston Published on September 1, 2014 02:15 PM Share Tweet Pin Email Photo: Ulises Ruiz Basurto/Landov Leandra Becerra Lumbreras has lived through every major historical event of the past century. On Sunday, her family says she made history herself. Born Aug. 31, 1887, the Mexican great-great-grandmother reportedly turned 127. But because she lost her birth certificate, the Guinness Book of World Records will not recognize her as the world’s oldest living person, the Telegraph reports. The former seamstress has outlived her five children, and her family tree extends as far as 55 great-great-grandchildren. In an interview with Mexico’s El Horizonte, she credits a love of chocolate and sleep with keeping her well. Not that Lumbreras left life pass her by: She says she served in the 1910 Mexican Revolution as the leader of Las Adelitas, a group of women in combat, according to the International Business Times‘s translation. “She is entirely lucid. She blows your mind with stories from the revolution,” Lumbreras’s granddaughter told El Horizonte. “She was always a woman who fought.” Want more stories like this?
