Misao Okawa, the world's oldest person, died on Wednesday at the age of 117. Members of her family told the Associated Press that Okawa died of heart failure and stopped breathing at her nursing home in Osaka, Japan.
Okawa had turned 117 only a few weeks ago, and was recognized by the Guinness Book of World Records in 2013 for being the oldest person on the planet. When asked for her secret to longevity, Okawa, the daughter of a kimono maker, said, "I wonder about that too."
