Does how long human beings are meant to live?
You must have heard this question lot of time since we had seen people who have crossed century and lived in different centuries like no other men’s. Till now, a woman named Jeanne Louise Calment has lived the longest. She was 122 years 164 days when she left the earth.
She died in 1997, Arles France where she lived long and happy life. She was the last reported person above 120 years.
A theory proposed by Benjamin Gompertz in 1825 said that the chances of death increases also called ‘mortality rate’ as we tend to grow older. This is known as Gompertz law which means the odds of dying double every eight years.
Some researchers didn’t consider this theory and told that at some point mortality rates decelerates which happens at the oldest age. Considering this it increases to 80 and then slows down after that to 100.
But not many are able to live up to that point. 2 out of 100,000 women have live to 100 age in case of men this number is outrageously as low as 2 in 1,000,000 at age 105. This study has been praised by many researchers and it proved the truth to a certain point. Italy is likely to have the best data we have,” Wachter said.
Similarly, more paper was published about the future mortality rate from the data collected from Japan and western countries which predicted the future age to be as high as 128 which is later rejected by Rootzen.
Like this researcher from Albert Einstein College of Medicine argued in Nature, gather data from 40 countries based on longevity and it was found that the limit was 115. A women name Calmet was an exception in this case as she lived till 120 years even after having 2 cigarettes a day.
Later she left it a year before she died because she came to know about her sickness. Many researchers argued on 115 age since there more than one example of people crossing 120 but failed to prove their point.
