Summary –
According to new research, even if cures for all serious diseases like cancer and heart disease are found in the future, human life still has a natural limit. Scientists say that there are some cells in the body that do not regenerate, and these determine the maximum limit of human life.
……………………………………………………….
Elaboration –
Scientists around the world have been working on increasing the human lifespan for a long time. New medicines, anti-aging technologies, and modern medicine have certainly made life longer than before, but can any human ever live up to 200 years? A new research by Russian scientists points towards a “no” for this question. So let us know what the scientists have explained.
………………..
What do scientists say ?
…………………………………………………..
Researchers from the Skolkovo Institute of Science and Technology and the Artificial Intelligence Research Institute have prepared a mathematical model that estimates the maximum limit of human lifespan. According to the study, even if complete cures for cancer, heart disease, and other fatal diseases are found in the future, the human lifespan can only remain around 156 years. Under very exceptional circumstances, a person might live up to 194 years, but going beyond that is currently considered impossible.
………….
What is the biggest reason behind this after all ?
……………………………………………………….
According to scientists, the most crucial reason is somatic mutations occurring in the body over time. These are minor changes in DNA that continuously accumulate as age increases. Gradually, their impact begins to affect the functioning capacity of vital organs in the body.
…………..
Why do brain and heart cells become the biggest challenge ?
………………………………………………………
Many parts of our body, such as skin and liver cells, regenerate from time to time. This allows them to repair themselves to a large extent. However, neurons in the brain and muscle cells in the heart do not divide again once they are formed. This is the reason why the damage occurring in them accumulates over time.
……..
In which direction will future research head ?
…………………………………………………………………
Researchers believe that this study can show a new direction for anti-aging research. They state that merely finding cures for diseases will not be enough. The biggest challenge in the future will be keeping those cells of the brain and heart healthy for a long time that cannot regenerate themselves. Scientists will further incorporate causes like mitochondrial dysfunction and telomere shortening into this model to understand the limits of human lifespan even better. Therefore, it would not be wrong to say that no human can live beyond 200 years.
