🌿 Longevity: What It Means, Key Terms and Can We Live to 100 Years?

In recent years, longevity has become one of the most fascinating topics in health, nutrition and wellbeing. From advances in regenerative medicine to healthy lifestyle habits, many of us are asking: how long can we really live—and how can we live better?

In this article, we explore what longevity truly means, the key terms used by experts, and whether it is really possible to live up to 100 years—or beyond. Most importantly, we look at whether longevity is about living longer or living better.

🧬 What is Longevity?

Longevity refers to the length of time a person lives, as well as the ability to maintain healthy biological functions throughout life. It is not just about living more years, but about living with health, vitality and quality of life.

Scientists usually distinguish between:

• Life expectancy: the average number of years a person is expected to live based on population statistics. According to the World Health Organization, global life expectancy is around 73 years.
• Maximum lifespan: the theoretical limit of human life. The current verified record belongs to Jeanne Calment, who lived to 122 years.
• Healthspan: the number of years lived in good health, free from major chronic diseases. Ideal longevity combines long life with high quality of life.

🔑 Key Terms in Longevity

Some commonly used terms in longevity research include:

• Gerontology: the study of ageing and its impact on health.
• Cellular senescence: the process by which cells stop dividing and contribute to ageing.
• Telomeres: protective caps at the ends of chromosomes; their shortening is linked to ageing.
• Caloric restriction: reducing calorie intake without malnutrition, associated with increased lifespan in some studies.
• Biomarkers of ageing: biological indicators used to measure biological age versus chronological age.
• Extreme longevity: individuals who live beyond 110 years, known as supercentenarians.

🔬 Could We Live to 150 Years?

The idea of living to 150 years or more has been explored in science and popular culture. Today, research offers some promising insights:

• Regenerative therapies: advances in stem cells, senolytics and telomere science may slow or reverse cellular ageing.
• Gene editing: technologies like CRISPR could help prevent genetic diseases linked to ageing.
• AI and personalised medicine: allow prediction of disease risks and optimisation of lifestyle based on individual biology.

📊 Interesting fact: while global life expectancy increases slowly each decade (~73 years today), the number of people living beyond 110 has grown significantly in recent years.

However, living to 150 remains hypothetical and would require major medical breakthroughs, lifestyle changes and genetic factors. Most experts agree: longevity is not just about years, but about quality of life.

⚖️ Longevity: Years or Quality of Life?

A central question in longevity is: do we want to live longer—or live better?

• More years: extending lifespan regardless of health conditions
• Better life: focusing on mobility, energy, mental wellbeing and disease prevention

Research shows that simple habits can significantly improve healthy lifespan:

• A plant-based, antioxidant-rich diet
• Regular physical activity (at least 150 minutes per week)
• Quality sleep and stress management
• Avoiding smoking and excessive alcohol

📌 Interestingly, healthy centenarians often share similar lifestyle patterns: balanced nutrition, moderate activity, strong social connections and a positive mindset.

📊 Longevity in Numbers

• Verified human longevity record: 122 years (Jeanne Calment)
• The FOXO3 gene, linked to longevity, is present in around 15% of the population
• Countries like Spain and Japan have life expectancies above 83 years
• By 2050, average life expectancy could exceed 90 years

✨ Conclusion

Longevity is not just a number—it is a balance between lifespan and quality of life. While living up to 150 years remains in the realm of advanced research, we already have powerful tools to live longer and better.

Healthy habits, medical innovation and conscious lifestyle choices are key to maximising longevity and enjoying a full, vibrant life.
