Scientists Explain Biggest Hurdle to Humans Living Beyond 200
Scientists are trying to figure out if people could ever live to be 200 years old.
Right now, the oldest person ever confirmed lived to 122.
Most people probably will not live much past 120 or 150 years.
The reason is that our bodies get damaged as we grow older.
Every day, tiny mistakes happen inside our cells, like typos in our DNA.
These mistakes pile up over time and make our body work worse.
Some parts of our body, like our brain and heart, cannot fix themselves very well.
Scientists are working on things like special medicines and cell repair to help.
But even if they succeed, living to 200 is still just a theory for now.
For now, scientists want to help people stay healthy for as long as they live.
Scientists say humans could theoretically live beyond 200 years, but accumulated biological damage is the biggest hurdle.
The longest confirmed human lifespan is 122 years, with most people unlikely to live beyond 120 to 150 years.
Cells accumulate DNA mutations over time that researchers describe as a fundamental, unavoidable part of biology.
Organs like the brain and heart have limited ability to repair themselves, placing a ceiling on human lifespan.
Researchers are exploring gene editing, stem cell therapies and anti-ageing drugs, while focusing on extending healthspan.
