Scientists reveal maximum age humans could live to if we can cure ageing
Yahoo News Canada • • health
Key Points:
- A new study suggests human lifespan may be capped at around 200 years even if advanced anti-ageing treatments eliminate all causes except DNA mutations in somatic cells.
- Researchers developed a mathematical model simulating organ deterioration due to accumulating somatic mutations, assuming other ageing factors like chronic inflammation and mitochondrial dysfunction are reversed.
- The brain and heart are most vulnerable to mutation damage due to their irreplaceable cells, while organs like the liver can better regenerate, influencing overall lifespan limits.
- The model predicts a median lifespan of 146-194 years under mutation-driven ageing alone, roughly double the current average of 79 years, indicating other ageing factors also significantly limit lifespan.
- Scientists emphasize the theoretical nature of the findings and highlight that DNA mutations will likely remain the primary barrier to extreme human longevity if other ageing mechanisms are overcome.
