Jiroemon Kimura is officially the world's oldest living person at the age of 115 as of this month.

The former postal employee has 14 grandchildren, 25 great-grandchildren and 13 great-great-grandchildren.

Kimura was born on April 19, 1897, and lives with his son's family near Kyoto, Japan, and became the world's oldest person following the death of Dina Manfredini in December. The Iowa native died on Dec. 17 at the age of 115 at a retirement center only two weeks after earning the title of world's oldest human. The previous holder of the oldest man ever title was Christian Mortensen, a Danish-American who lived until the age of 115 before dying in 1998. 

Kimura is also the last living man from the 19th Century. He was 6 years old at the time of the Wright Brothers' first flight and was 64 when Yuri Gagarin became the first person in space.

Guinness World Records Editor-in-Chief Craig Glenday traveled to Japan to hand deliver a copy of the Guinness World Records 2013 to Kimura, whom he called "an exceptional person."

Glenday said Kimura is only the third man in history to reach the age of 115 and the first Japanese man to reach that same age.

As far as a daily routine, Kimura's Facebook page stated that he "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." 

When asked by the Telegraph about the secret to his longevity, he replied, "I don't know exactly... maybe it's all thanks to the sun above me. I am always looking up towards the sky, that is how I am."
