Jeanne Calment: The Record Holder
Jeanne Louise Calment, a French supercentenarian, holds the undisputed record for the longest documented human lifespan. Born in Arles, France, on February 21, 1875, she lived until August 4, 1997, witnessing profound historical changes from the invention of the airplane to the dawn of the internet age. Her extraordinary age of 122 years and 164 days has been thoroughly investigated and verified, setting a benchmark for extreme longevity.
Calment's longevity captured the attention of demographers and gerontologists worldwide, including Jean-Marie Robine and Michel Allard, who formally validated her case. Her long life was filled with intriguing anecdotes, such as meeting Vincent van Gogh in her uncle's shop at age 13. Despite outliving her husband, daughter, and grandson, she maintained a sharp wit and a lively spirit, even releasing a rap CD at age 121.
The Verification of Calment's Age
Verifying an individual's age, especially for supercentenarians (people who live to 110 or older), is a meticulous process. In Calment's case, verification was supported by a wealth of documentation, including census records stretching back to 1876. Her longevity claim was briefly questioned in 2018, proposing her daughter may have assumed her identity. However, subsequent analyses by the original researchers and other experts reaffirmed her record based on the strength of the original evidence, confirming her place in history.
The Pursuit of Longevity: Genetics vs. Lifestyle
Calment's story raises a fundamental question in the study of aging: what is the secret to extreme longevity? Scientists point to a complex interplay of genetic factors and lifestyle choices. While Calment herself credited olive oil and port wine, the science is far more intricate.
The Genetic Angle
Research into the genetics of longevity suggests that a combination of multiple genes, each with a small effect, contributes to an extended lifespan. Notable examples include the APOE gene, where certain variants are associated with a higher risk of Alzheimer's and a shorter lifespan, while others are linked to increased longevity. Another significant gene is FOXO3, which has been consistently associated with increased lifespan across diverse populations. Centenarian studies show that those with exceptional longevity often carry just as many disease-associated genetic variants as the average person, suggesting their genetic advantage lies in variants that delay aging rather than a complete absence of risk factors.
The Lifestyle Contribution
While genetics can provide a head start, lifestyle choices play a significant role. Numerous studies have highlighted the importance of factors like diet, exercise, and social engagement.
- Diet: Centenarian studies, such as the Chinese Longitudinal Healthy Longevity Survey, indicate that a diverse diet is linked to a higher probability of becoming a centenarian. In Japan, which boasts a high centenarian population, traditional diets low in fat and red meat contribute to reduced rates of heart disease and cancer.
- Exercise: Regular physical activity, even in old age, is strongly associated with improved health outcomes and longevity. Calment famously took up fencing at 85 and rode a bicycle until 100, demonstrating a lifelong commitment to activity.
- Stress Management: Stress has a significant impact on health. A positive outlook and effective coping mechanisms, like Calment's famously carefree attitude, have been observed in many long-lived individuals.
The Science of Aging and Lifespan
Researchers continuously investigate the underlying mechanisms of aging to understand why some people live so much longer than others. Key areas of study include:
- Telomere Maintenance: Telomeres are protective caps on the ends of chromosomes that shorten with each cell division. Some longevity-associated genes are involved in maintaining telomere length, which can slow cellular aging.
- DNA Repair: The ability of cells to repair DNA damage is crucial for longevity. Studies show a correlation between species lifespan and their DNA repair capabilities.
- Inflammation and Oxidative Stress: Chronic inflammation and damage from unstable oxygen molecules (oxidative stress) contribute to aging. Genes that protect against these processes are linked to longer lives.
Comparing Top Verified Supercentenarians
Examining the world's longest-lived individuals reveals fascinating differences and similarities. All of the top ten verified supercentenarians are women, a pattern that reflects the general trend of women having longer average life expectancies. The table below compares the top verified individuals with Jeanne Calment.
| Rank | Name | Age (Years, Days) | Country | Birth Year | Death Year |
|---|---|---|---|---|---|
| 1 | Jeanne Calment | 122 years, 164 days | France | 1875 | 1997 |
| 2 | Kane Tanaka | 119 years, 107 days | Japan | 1903 | 2022 |
| 3 | Sarah Knauss | 119 years, 97 days | USA | 1880 | 1999 |
| 4 | Lucile Randon | 118 years, 340 days | France | 1904 | 2023 |
| 5 | Nabi Tajima | 117 years, 260 days | Japan | 1900 | 2018 |
The Maximum Biological Lifespan
For decades, scientists have debated whether there is an upper limit to the human lifespan. The sheer rarity of individuals living past 110, and Calment's singular case beyond 120, suggests there may be a biological cap. Some mathematical models estimate this limit to be around 125 years. However, others argue that as medical advances continue to treat and prevent age-related diseases, both average and maximum lifespan could be extended. The New England Centenarian Study, among others, continues to explore the genetic, environmental, and lifestyle factors that enable exceptional survival, providing a rich source of data for further research.

Conclusion: A Combination of Fortune and Fortitude
Ultimately, the record of who is the oldest person to ever live belongs to Jeanne Calment, a woman whose life defied statistical probability. Her story is a testament to the powerful combination of a robust genetic makeup and an active, low-stress lifestyle. While most people may not reach such an extreme age, the study of Calment and other supercentenarians provides crucial insights. Their lives confirm that while some luck is undoubtedly involved, focusing on modifiable lifestyle factors like diet, exercise, and maintaining social connections can significantly influence a person's chances of living a long, healthy life. As research into aging accelerates, the hope is not just to extend the maximum lifespan, but to extend the healthspan—the period of life lived in good health—for everyone.
