Kane Tanaka wakes up at 6 a.m. each day, likes to study math and other subjects for fun and competes fiercely in the board game Othello, ONA reports quoting USA Today.
It's proven to be a pretty good combination for the 116-year-old from Fukuoka, Japan.
Tanaka was named Saturday the new oldest living person in the world by the Guinness Book of World Records.
She was recognized at a ceremony at her nursing home where she was given a commemorative framed certificate and a box of chocolates. She started eating the chocolates immediately, Guinness said, and responded with "100" when asked how many she planned to eat that day.
Tanaka, the youngest of seven children of Kumakichi and Kuma Ota, was born prematurely on Jan. 2, 1903. Theodore Roosevelt was president of the United States and World War I was still a full decade away from changing geopolitics forever.
She married Hideo Tanaka at 19, before they had ever met, following a Japanese norm at the time. The couple went on to have four children and adopt a fifth.
