Sister André, a French nun who held the title of the world's oldest person, died Jan. 17 at age 118 in Toulon, a city in southern France.

Born Lucile Randon on Feb. 11, 1904, she "dedicated most of her life to religious service," according to Guinness World Records(opens in new tab). As a young woman, she served as a teacher and later as a governess (private tutor) during World War II. After the war ended, she worked with orphans and the elderly at a hospital in Vichy, France, but it wasn't until 1944, at age 40, that she took vows to become a Catholic nun and changed her name to Sister André.

Guinness World Records declared Sister André not only the world's oldest person but also the oldest nun on record. (She earned the former title in April 2022, after the passing of Kane Tanaka, a 119-year-old Japanese woman.) Sister André was also the oldest person in Europe to survive COVID-19, being released from the hospital in time to celebrate her 117th birthday.

"I didn't even know that I had it," Sister André told Var-Matin(opens in new tab), a French newspaper, in a translated statement. 

For Sister André’s 118th birthday, French President Emmanuel Macron sent her a handwritten birthday card congratulating her on her long life of service — he was the 18th French president to hold office during her lifetime, according to CNN(opens in new tab).

While it's easy to speculate what led to her longevity, when pressed, Sister André once chalked it up to her enjoyment of indulging in chocolate and a glass of wine each day. She also told CNN, "I feel I would be better off in heaven, but the good Lord doesn't want me yet."

For anyone hoping to reach a similar age as Sister André, eating high-quality dark chocolate may have a few health benefits, such as protecting against heart failure in women and possibly lowering blood pressure and decreasing the risk of stroke. However, while wine may protect against a few health conditions, such as lowering the risk of heart disease, there isn't much evidence suggesting that it may lead to a longer life.

Sister André was three years shy of earning the title of the oldest person ever to live on record, which is held by Jeanne Louise Calment(opens in new tab), a fellow Frenchwoman who died Aug. 4, 1997, at age 122, according to Guinness World Records.
