Jiroemon Kimura, of Japan, is the only man alive who was born in the 1800s.
Kimura was born on April 19, 1897 and is currently the oldest human at 116.
He has literally watched history unfold before his eyes. He has lived through two world wars, four Japanese emperors and 61 Japanese prime ministers.
According to The Sydney Morning Herald, Kimura retired in 1962 when he was 65.
Kimura worked for 45 years for the post office and has been living out his days in Kyo Tango, Kyoto Prefecture, Japan.
He attributes his longevity to small portions of food and spending most of his later years in bed.
Kimura is cared for by his eldest son's widow, 83, and his grandson's widow, 59.
