In 1986, Cuyahoga Falls merged with Northampton Township, the first merger of a city and township in Ohio. Cuyahoga Falls had been founded as an industrial city, taking advantage of the river power. By the 1970s, though, it had become a residential community.
Guinness World Records says the oldest living person verified by original proof of birth is Misao Okawa, a 115-year-old Japanese woman. The oldest verified age was 122 years and 164 days: Jeanne Calment of France, who died in 1997.
More evidence of Calment's lifespan has been produced than for any other supercentenarian; her case serves as an archetype in the methodology for verifying the ages of the world's oldest people. As women live longer then men, combined records for both sexes are dominated by women. The longest undisputed lifespan for a man is that of Jiroemon Kimura of Japan (1897â2013), who died at age 116 years, 54 days. He was also the world's oldest living person from December 2012 until his death. Since the death of 116-year-old Jeralean Talley of the United States on 17 June 2015, Susannah Mushatt Jones also of the United States, born 6 July 1899, is the oldest living person in the world whose age can be documented.
