Jeanne Calment, officially the longest-lived human ever, died in 1997 at 122 years and 164 days, leaving the world amazed. Her longevity, despite a love of chocolate, wine, and cigarettes, has fascinated scientists and the public alike.

Born in 1875 in Arles, France, Calment’s age has been thoroughly verified through birth certificates, census records, marriage documents, and photos. Guinness World Records recognizes her as the only person confirmed to have lived past 119.

Her life spanned three centuries and extraordinary historical events. She witnessed the rise of electricity, telephones, and automobiles, the construction of the Eiffel Tower, two World Wars, and the emergence of the internet. She also observed major social and political shifts, including the American Civil Rights Movement.

Remarkably, Calment remained active well into old age. She rode her bicycle into her 90s, and on her 100th birthday, she walked through Arles to thank well-wishers. She stayed socially engaged, mentally sharp, and physically mobile long past the age most people retire from public life.

Her lifestyle surprised many. She ate nearly two pounds of chocolate weekly, enjoyed dessert with every meal, drank port wine in moderation, and smoked from age 21 until 117. Despite these habits, she largely avoided chronic illnesses associated with such behaviors.

Calment was known for her wit and humor. At 120, she said, “I see badly, I hear badly, I can’t feel anything, but everything’s fine,” and joked about having “only one wrinkle—and she was sitting on it.”

Researchers suggest her emotional resilience may have been key to her longevity. Jean-Marie Robin, who studied her closely, noted that Calment seemed “immune to stress,” a trait she summarized: “If you can’t do anything about it, don’t worry about it.”

Calment’s life demonstrates that mental resilience, social engagement, humor, and staying active may be as important as biology in aging. While few will reach her age, her story inspires a focus on emotional calm and curiosity as a path to a long, fulfilling life.
