Some people in the world live for 100 years or more. The number of centenarians in Japan is more than 86 thousand. Recently there is a record of a lady in France who lived for 122 years. But compared to the world’s population of 7 billion, the number of centenarians is very small, only 0.004% of the total population. Very few people in the world can celebrate their 100th birthday.
Another thing to note is that although the average life expectancy of people has doubled in the last hundred years, people have not yet conquered old age. Ignoring old age, how many years can people live in a healthy body? This is a huge question. As we all know, the human body becomes fragile as we age. In old age, human bones become weak, muscles become loose, skin becomes uneven, eyesight becomes cloudy, and memory declines. The body becomes the home of various diseases. Then at some point, the human body can no longer take this pressure. People are slowly falling into the arms of death. This is called the death of old age. We have accepted this as the natural end of life.
But scientists think that old age cannot be the end of human life. They researched ageing and realized that ageing is a disease and it is possible to cure this disease. The cause of ageing lies within the cells. Scientists have identified several biological causes of ageing. Scientists say that several genetic and epigenetic changes occur inside the living cells over time. These changes are responsible for overall ageing.
Scientists believe that ageing can be defeated if this process can be interrupted or reversed. They have achieved considerable success in this regard by researching mice. Scientists have identified several genes that could slow down the ageing process. They think the same applies to humans. It is possible to increase the lifespan of humans by controlling damaged DNA, telomere loss, histone modifications, mitochondrial defects, protein degradation, dysregulated metabolism, increased inflammatory molecules and depleted stem cells. Research is going on now.
