The Unprecedented Case of Jeanne Calment
Jeanne Louise Calment, born in Arles, France, in 1875, holds the record for the longest confirmed human lifespan. Her life spanned 122 years and 164 days, ending in 1997. Her longevity was extensively verified by experts. While questions about her age have been raised, the original research team reaffirmed the validity of her record. Calment's life was relatively comfortable; she didn't work a traditional job and enjoyed activities like cycling. Her diet included olive oil and port wine, and she smoked for a time. Her case provides insight into supercentenarians, those living to 110 or older.
Maximum Lifespan vs. Average Life Expectancy
It's important to distinguish between maximum lifespan and average life expectancy. Average life expectancy is a statistical measure influenced by factors like birth year and location. Maximum lifespan, however, refers to the biological upper limit of human life. Calment's record has stood for decades, leading some to propose a potential natural limit to human lifespan, although some research suggests the record may eventually be surpassed. Improvements in health have increased average life expectancy significantly.
The Science of Extreme Longevity
Studying supercentenarians like Calment is vital for understanding extreme longevity. Researchers examine genetic and environmental factors contributing to their advanced age. Genetics play a role, but lifestyle factors have a greater impact, especially earlier in life. Supercentenarians often experience "compression of morbidity," remaining healthy longer with illness concentrated at the end of life.

The Role of Genetics and Lifestyle in Longevity
Achieving extreme longevity involves both genetics and lifestyle choices. While some genes are linked to longer life, they are not a guarantee. A healthy lifestyle is the most significant factor within our control.
- Diet and Nutrition: Diets rich in whole foods, vegetables, and lean protein, similar to the Mediterranean diet, are common among centenarians. Populations in "Blue Zones" often follow plant-based diets.
- Regular Physical Activity: Moderate daily movement, like walking and gardening, is consistently observed in long-lived individuals.
- Strong Social Connections: Social bonds are correlated with longer survival and improved well-being.
- Stress Management: Managing stress through practices like meditation or having a sense of purpose (ikigai) is common in long-lived populations.
- Adequate Sleep: Sufficient sleep is crucial for health and supports long-term wellness.
How Longevity Research is Evolving
Studying supercentenarians provides insights into factors promoting longevity. Researchers use genetic sequencing to identify gene variants and understand their interaction with the environment. The focus is expanding to 'healthspan'—healthy years of life—aiming to improve life quality as well as length. Advancements in technology continue to enhance our understanding of aging. Research into cellular mechanisms and biomarkers aims to predict and influence aging. This research has the potential to transform healthcare and healthy aging.

The Future of Longevity
Jeanne Calment's record of 122 years is the current maximum. However, scientific models suggest the practical human lifespan may increase within this century, though the extent is debated. Breaking the record will depend on a deeper understanding of aging. The goal is to not only extend life but ensure it is healthy and vibrant.
