According to an article published by the New York Post, a woman named Leandra Becerra Lumbreras is unofficially recognized as the oldest living human being in the world, living to the age of 127 as of August 31, 2014. Her claim is supported by being able to recite accounts of events that she took part in 100 years ago, such as being a female soldier in the Mexican Revolution.
Lumbreras, however, is not recognized officially as the world's oldest living human being due to her birth certificate being destroyed decades before during a move. Her legitimacy has been verified through other sources, however, from judges going back through the places she has been and checking documents and witnesses that support the claim.
As of 2014, the officially recognized world's oldest human being is Misao Okawa, a Japanese woman who is 116 years old. She is directly followed by another Japanese record, the world's oldest man, Sakari Momoi. According to the article published about him in the New York Post, he was born on Feb. 5 1903, making him 111 years old as of 2014. He was given a certificate by the Guinness Book of World Records in recognition of holding the record.
