World's Oldest Man Ever: 115-Year-Old Jiroemon Kimura Breaks Guinness World Record

The World's Oldest Man ever is Jiroemon Kimura at the age of 115 years 253 days, according to Guinness World Records which confirmed his title on Thursday. Additionally, the Japanese also held the record as the Oldest Living Man and the Oldest Living Person.

Born April 19, 1897, Kimura broke the record for the Oldest Living Person on December 17, 2012, after the previous record holder Dina Manfredini of the United States died at the age of 115 years, 257 days.

But the world's oldest man ever to have lived is Jeanne Calment of France at the age of 122 years, 164 days.

Kimura is the third person in history to reach 115 years old. From 1914 until he was aged 65, he worked at the Post Office and then worked in agriculture until age 90.

What was Kimura's secret to be the world's oldest man ever?

According a message on a Facebook page dedicated to him, Kimura "wakes up early in the morning and reads newspapers with a magnifying glass. Also, he enjoys talking to guests and follows live parliamentary debates on television. According to him, small portions of food are the key to a long and healthy life."

His personal motto: "eat light to live long."

Kimura's record as the world's oldest man ever was first recognized by Gerontology Research Group, an international body that specializes in longevity research.

At age 115, Kimura has 14 grandchildren, 25 great-grandchildren and 13 great-great-grandchildren.
