Japan’s Jirouemon Kimura who lives in the western city of Kyotango, celebrated his 115th birthday at home.

Although he’s not able to move around much these days, spending most of his time in bed, he always makes it a point to eat three meals with this family on a daily basis.

Kimura’s birthday is April 19, 1897, and he has seven children, five of them who are currently living. With that being said, Kimura has 14 grandchildren, 25 great-grandchildren and 13 great-great-grandchildren.

The world’s oldest man worked up until he was 90, and endured a 38-long career at a local post office. When he retired from the post office, he farmed.

Kimura said one of his secrets is that he doesn’t eat to where he is full, stopping when he’s around 80 percent full.
