The World’s Oldest Person: Jeanne Calment
Born in Arles, France, in 1875, Jeanne Calment lived for 122 years and 164 days, passing away in 1997. Her story is the most thoroughly documented and validated case of extreme longevity in human history, confirmed by extensive records including birth certificates, census data, and her own interviews. Her longevity attracted immense media attention and scientific scrutiny, solidifying her place in history as the only verified person to live past the age of 120.
A life full of history
Calment's life spanned an incredible period of history. She was born before the invention of the telephone and lived long enough to see the rise of the internet. Here are some remarkable facts about her life:
- She reportedly met Vincent van Gogh in her father's shop in 1888, describing him as “very ugly” and “surly”.
- She outlived her husband, daughter, and grandson.
- At age 90, she famously signed a real estate deal, selling her apartment to a lawyer who agreed to pay her a monthly fee until her death. The lawyer died before her, and his family continued the payments for years.
The science of supercentenarians
The study of supercentenarians, people aged 110 or older, offers clues into the mechanisms of extreme aging. Jeanne Calment was a prime example, displaying characteristics that have since been observed in other exceptional agers.
Characteristics of extreme longevity
Research on supercentenarians reveals several common traits:
- Delayed disease onset: Many supercentenarians avoid or significantly delay the onset of major age-related diseases like heart disease, cancer, and diabetes.
- Genetic predisposition: Studies of supercentenarian siblings show a much higher probability of reaching extreme old age, suggesting a genetic component to their longevity.
- Compression of morbidity: Rather than experiencing a long period of decline, many supercentenarians remain relatively healthy and independent until the very end of their lives.
The importance of lifestyle and genetics
While genetics play a role in extreme longevity, they are not the sole determinant. Experts suggest that genetics account for only about 20% to 30% of a person's expected lifespan, with lifestyle and environmental factors playing a more significant role, especially in midlife. Calment herself attributed her longevity to things like a diet rich in olive oil, a glass of Port wine, and a positive outlook.
What limits the human lifespan?
The fact that Calment's record of 122 has stood since 1997 raises questions about whether there is a natural limit to the human lifespan. Scientists disagree on this point, with some arguing for a fixed maximum and others suggesting the ceiling is elastic.
A comparison of longevity theories
| Theory | Proponents | Core Concept | Evidence Supporting | Evidence Against/Counter-arguments |
|---|---|---|---|---|
| Wear-and-Tear | Oldest hypothesis | The body wears out like a machine over time due to accumulated damage. | Some accumulation of cellular waste products (e.g., lipofuscin) with age. | Biological systems have self-repair mechanisms, unlike machines. Not a complete explanation. |
| Genetic | Supported by twin studies | Longevity is programmed in our genes, with some inheriting more favorable traits. | Long-lived families often run in families; identical twins have more similar lifespans. | Genetics account for only 20-30% of longevity; environmental factors are critical. |
| Cellular Senescence | Telomere shortening theory | Cells have a limited number of divisions (Hayflick limit) and then stop reproducing. | Telomeres shorten with each cell division. Cell death contributes to aging. | Some long-lived species have shorter telomeres; other factors also contribute to cell death. |
| Oxidative Stress/Free Radical | Denham Harman, 1950s | Accumulated damage from highly reactive molecules (free radicals) leads to cellular dysfunction. | Antioxidant abundance in older cells; caloric restriction may lower oxidative stress. | Antioxidant supplements have not consistently shown benefits; role is complex and not fully understood. |
Can we break the 120-year barrier?
Jeanne Calment's long life was an extraordinary outlier, but recent research suggests that her record may eventually be broken. A 2021 University of Washington study, using modern statistics, found a near 100% probability that the 122-year record will be surpassed this century. This is driven not by any single breakthrough but by a growing population of older adults and a higher number of supercentenarians, which increases the likelihood of a statistical anomaly like Calment's life occurring again.
The search for the secrets of extreme longevity continues. Researchers study centenarians and supercentenarians to understand the unique genetic and environmental factors at play. The focus has shifted from simply extending life to extending healthspan, the number of years lived in good health. This holistic approach to aging science could one day make living past 120 a more common, if still exceptionally rare, occurrence.
The role of modern medicine
Advances in medical science, from diagnostics to preventative care, are pushing the boundaries of what is possible. While treatments for specific diseases extend the lifespan, the burgeoning field of geroscience focuses on the aging process itself. By targeting the fundamental mechanisms of aging, such as cellular senescence and inflammation, scientists hope to prevent chronic diseases simultaneously. This research is paving the way for a future where extended healthy longevity is a realistic goal for a larger portion of the population.
The path forward for healthy aging
Regardless of whether a person reaches 120, the lessons from longevity research are applicable to everyone. Simple lifestyle choices can significantly influence health and extend life.
- Healthy Diet: A balanced, nutrient-rich diet with plenty of fruits, vegetables, whole grains, and healthy fats is key.
- Regular Exercise: Physical activity helps maintain a healthy weight, boosts mood, and lowers the risk of chronic diseases.
- Stress Management: Chronic stress can accelerate aging. Techniques like mindfulness and meditation can help manage stress effectively.
- Mental Engagement: Keeping the mind active through reading, puzzles, and social interaction is crucial for cognitive health.
The story of Jeanne Calment proves that the human body is capable of extraordinary feats of longevity. While she remains an outlier, her life, and the subsequent study of supercentenarians, provides invaluable insight into the potential of healthy aging for us all.

Conclusion
The question, has anyone lived over 120 years?, is answered by the singular and well-documented case of Jeanne Calment, who lived to 122. Her life, while a fascinating anomaly, demonstrates that the human lifespan is not a hard-and-fast limit. Scientific research into supercentenarians continues to unlock the secrets behind extreme longevity, revealing a complex interplay of genetics, environment, and lifestyle. While reaching 120 may be a rarity, the quest to understand it drives broader advances in healthy aging, offering a path to extending healthspan and vitality for everyone. By adopting healthy habits and staying engaged, we can all aim to live our longest, healthiest lives possible.
