The World's Oldest Verified Person
While claims of people living to 140 or older exist, none are independently verified by modern longevity research standards. Organizations like the Gerontology Research Group and Guinness World Records require documentary evidence such as birth records, which are often missing for historical or exceptionally old individuals. This strict process means no human has been proven to reach 140.
The case of Jeanne Calment
Jeanne Calment of France holds the verified record for the longest human lifespan at 122 years and 164 days. Born in 1875 and living until 1997, her age is thoroughly authenticated by experts despite some contested claims. She is the benchmark for documented human longevity.
Limits and Theories of Human Lifespan
Scientists debate the potential limits of the human lifespan. Some theories suggest a biological maximum, while others propose future advancements could extend it significantly. Factors influencing longevity include genetics, lifestyle (diet, exercise, avoiding smoking), healthcare, sanitation, and environment (like those in "Blue Zones").
Comparison of Verified vs. Alleged Longevity
A comparison between verified and alleged long-lived individuals highlights the criteria for authentication. Verified cases, like Jeanne Calment (122 years), rely on strict birth and identity documentation and are accepted by scientific consensus. Alleged cases, some claiming 140+ years (e.g., Mbah Gotho, Habib Miyan), often lack reliable documentation and are dismissed by gerontologists as unverifiable. Verified records are typically from the era of modern record-keeping, while alleged cases often pre-date these systems.
Could we ever live to 140?
While no one has reached 140 with current evidence, future possibilities are debated. Some experts suggest a fundamental biological limit between 120 and 150 years, while advances in medicine and genetics might potentially extend lifespan further. Research into aging continues to inform this discussion.
Conclusion
No human has been verified to have lived to 140 years old. Jeanne Calment's record of 122 years stands as the highest documented age. Unsubstantiated claims exist but lack rigorous proof. The possibility of reaching 140 is a scientific debate, with theories on biological limits contrasting with potential future medical breakthroughs. {Link: GRG Supercentenarians https://www.grg-supercentenarians.org/}.
