The World Record Holder
Jeanne Louise Calment of Arles, France, holds the Guinness World Record for the longest documented lifespan in history. Born on February 21, 1875, she lived until August 4, 1997, when she passed away at the age of 122 years and 164 days. Her extraordinary longevity far exceeds that of any other supercentenarian, and her life story offers a rare glimpse into the factors that can contribute to an exceptionally long life.
Life and Habits of Jeanne Calment
Calment's life was well-documented, spanning 17 census records and numerous civil registrations. Born into a bourgeois family, she lived a relatively stress-free life, enjoying hobbies like tennis, cycling, and opera. Her daily routine included coffee with milk and rusks for breakfast, a diet rich in olive oil, and sometimes up to two pounds of chocolate per week. She also famously quit smoking at 117 because she was too blind to light her own cigarettes. Despite her unconventional lifestyle, researchers studying her found her cognitive function to be relatively sharp even in her later years.
Controversy and Scrutiny of the Record
While Jeanne Calment's record is widely accepted, it has not been without controversy. In 2018, Russian researchers proposed a theory of identity fraud, suggesting that Calment's daughter, Yvonne, had assumed her mother's identity in 1934 to avoid inheritance taxes. This theory sparked a renewed debate among gerontologists and demographers. However, the original validation team, along with other researchers, have stood by their initial findings, citing extensive evidence including census data, notarial documents, and her verifiable correct memories of 19th-century events that her daughter would not have known. Most experts conclude that the evidence in favor of Calment's authentic age is far stronger than the circumstantial claims of fraud.
Other Notable Supercentenarians
Jeanne Calment is the only person to have definitively lived past 120. The next longest-living individuals, also female, reached ages just under 120. The top verified lifespans show how rare and exceptional extreme longevity is.
| Rank | Name | Age | Country | Year of Death |
|---|---|---|---|---|
| 1 | Jeanne Calment | 122 years, 164 days | France | 1997 |
| 2 | Kane Tanaka | 119 years, 107 days | Japan | 2022 |
| 3 | Sarah Knauss | 119 years, 97 days | United States | 1999 |
| 4 | Lucile Randon | 118 years, 340 days | France | 2023 |
| 5 | Nabi Tajima | 117 years, 260 days | Japan | 2018 |
The Science of Extreme Longevity
Research into human lifespan suggests that reaching ages like 120 is exceptionally rare and influenced by a combination of genetics and lifestyle.
The Role of Genetics
- Predisposition: Studies of supercentenarians and their families indicate a strong genetic component to extreme longevity. Certain genetic variants are more common among the exceptionally old, potentially protecting them from age-related diseases.
- Counteracting Variants: Interestingly, some long-lived individuals possess disease-associated gene variants but also have protective variants that counteract their effects.
- Epigenetics: Lifestyle factors can influence gene expression, a field known as epigenetics. This means that while genetics set the stage, lifestyle choices can help unlock a person's genetic potential for a long life.
The Importance of Lifestyle
Beyond genetics, healthy lifestyle choices are critical, especially for those in the 60-80 age range.
- Dietary Habits: Many studies highlight the benefits of a balanced diet, such as the Mediterranean diet, rich in whole grains, vegetables, and healthy fats. Some research also points to calorie restriction as a factor.
- Physical Activity: Regular, moderate physical activity is a common trait among long-lived populations, often integrated into daily life rather than formal gym routines.
- Social Connections: Strong social ties and community engagement are linked to better health outcomes and longer lifespans.
- Stress Management: A positive attitude and effective stress management techniques are frequently cited by supercentenarians as crucial for their well-being.

Conclusion: Pushing the Limits of Human Lifespan
While Jeanne Calment remains the sole verified person to have exceeded 120 years, her case provides valuable insights into the extreme limits of human aging. The science suggests that extreme longevity is a complex interplay of genetic predisposition and positive lifestyle factors. While reaching 120 might require a rare combination of favorable genes and good fortune, the habits of supercentenarians—including healthy diet, regular activity, and strong social bonds—offer a blueprint for a healthier, longer life for all of us. Research continues to explore the mechanisms of aging, offering hope that future generations may see more individuals approaching, and potentially even surpassing, this remarkable milestone.
