The World Record Holder: Jiroemon Kimura
Jiroemon Kimura was born on April 19, 1897, in the fishing village of Kyotango, Japan. His life spanned three centuries, witnessing immense global changes from the late 19th century into the modern digital age. Kimura lived a relatively quiet life, working for the post office until he retired, after which he took up farming until he was 90 years old. He passed away on June 12, 2013, at the age of 116 years and 54 days, a record officially recognized by Guinness World Records.
His longevity became a subject of great interest, and while he did not claim to have any particular secret, his lifestyle provides clues. Kimura was known for his disciplined and active life. He maintained a diet that was reportedly light, eating in moderation, and was engaged socially with his family and community. He exemplified a lifestyle where physical and social activity remained central well into his final years.
Beyond the Record: Other Remarkable Supercentenarians
While Kimura holds the male record, studying other supercentenarians provides a broader perspective on longevity. One of the most famous examples is Jeanne Calment, a French woman who lived to 122 years and 164 days, holding the record for the oldest documented and verified human lifespan. Comparing the health and lifestyle factors of these individuals reveals common threads that scientists believe are key to extreme longevity.
What We Can Learn from Extreme Longevity
Studying individuals like Jiroemon Kimura and Jeanne Calment allows gerontologists to explore the complex interplay of factors contributing to extreme old age. The science of longevity, known as gerontology, examines biological, psychological, and sociological aspects of aging.
Genes and the Role of Immunity
Researchers have identified specific immune system adaptations in centenarians. Studies suggest that these individuals may have developed faster and more effective immune responses to infections over their lifetimes. In addition, specific genes related to DNA repair and inflammation have been associated with extreme longevity. This research, though still preliminary, indicates that a resilient immune system and certain genetic variations can play a protective role, enabling some people to recover from disease and live to exceptionally old ages.
Lifestyle Habits of the Very Old
Long-lived individuals often share similar lifestyle habits, many of which are well-known pillars of healthy aging. These include:
- Diet and Nutrition: A balanced diet rich in fruits, vegetables, and lean proteins, and low in empty calories, is a recurring theme. The Blue Zones, regions with a high concentration of centenarians, are famous for their plant-based diets.
- Regular Physical Activity: Maintaining an active lifestyle, even with low-intensity activities like walking, gardening, or tai chi, is crucial for promoting mobility, circulation, and overall well-being. Jiroemon Kimura's post-retirement farming is a prime example.
- Strong Social Ties: Research consistently links strong social connections to improved mental and physical health in older adults. Isolation and loneliness are considered risk factors for various health problems. Many centenarians remain actively engaged with their communities and families.
- Stress Management: Chronic stress can take a toll on the body and brain. Many long-lived people report having a calm disposition or practice stress-reducing activities like meditation.
Comparing Male and Female Longevity
While Jiroemon Kimura holds the record for men, the overall record for longest lifespan belongs to a woman. This pattern is not an anomaly; worldwide, women, on average, tend to live longer than men. The reasons for this disparity are complex and not fully understood, but potential factors include differences in genetics, hormones, and lifestyle.
| Factor | Male Longevity (Generally) | Female Longevity (Generally) |
|---|---|---|
| Cardiovascular Health | Men are at a higher risk of heart disease earlier in life. | Women are often more protected from heart disease until menopause. |
| Genetics | Only one X chromosome, which may make them more susceptible to certain genetic diseases. | Two X chromosomes, which may offer a protective redundancy. |
| Lifestyle Risk Factors | On average, men are more likely to engage in riskier behaviors, such as smoking and heavier alcohol consumption. | On average, women are less likely to engage in these behaviors, though trends are shifting. |
| Hormonal Differences | Testosterone has been linked to potential cardiovascular risks. | Estrogen is thought to have a protective effect on cardiovascular health. |
| Immune Response | Some research suggests differences in immune system strength and function. | Some studies show women may have stronger immune responses to infections. |
The Psychology of Healthy Aging
The mindset of individuals who live exceptionally long lives is another area of focus for researchers. While physical health is paramount, psychological well-being is often a shared trait. A positive outlook, a sense of purpose, and resilience are frequently observed in centenarians. Jiroemon Kimura himself was noted for his calm demeanor, a trait that may have contributed to his overall health. The ability to adapt to changes and maintain a sense of fulfillment throughout life is a powerful, yet often overlooked, component of healthy aging.
The Longevity Blueprint
While genetics provide a foundation, the stories of the oldest men and women in history show that behavior and environment play a significant role. The “secret” to long life is not a single factor but a combination of many, including:
- A balanced, nutrient-rich diet.
- Consistent physical activity.
- Robust social and family connections.
- Effective stress management.
- An optimistic and resilient mindset.
For most people, the goal is not merely to extend life, but to extend health—the period of life spent free of disease and disability. The lessons from centenarians show that focusing on these pillars can lead to a longer, more vibrant life, whether one breaks a world record or not.

Conclusion: A Living Legacy
Jiroemon Kimura's record-setting life is a testament to the potential for human longevity. His story, along with those of other supercentenarians, serves as an inspiration for the pursuit of healthy aging. By understanding the combination of genetic luck and lifestyle choices that led to these extraordinary lifespans, we can better inform our own decisions for a longer, more active, and more fulfilling life.
The search for the secrets of extreme old age continues to drive research in gerontology. While not everyone can live to 116, the valuable lessons from those who have can help us all build a healthier foundation for our later years, making the most of the time we are given.
