The 122-year-old longevity record may be refreshed

  Many people think that human lifespan has reached its limit, but new research shows that the longevity record of 122 years old will be refreshed in the next 40 years. The research was published in the recently published “PLOS ONE” journal.
  The scientists analyzed mortality data for hundreds of millions of people in 19 countries who were born between the 18th century and the 1960s. The researchers used an existing mathematical model to explore the differences in the mortality rate of people aged 50 to 100 in different birth years, and then used this information to predict people’s future longevity age.
  Scientists have long debated the age limit for human longevity, which was previously thought to be 150 years old. But in the past 25 years, no one has broken the world record for longevity held by Jean-Louise-Calmont, who died in 1997 at the age of 122. David McCarthy, an associate professor at the University of Georgia in the United States, said that in most of the countries surveyed, it is expected that the age of human longevity will increase rapidly, and the record for human longevity will be set in the next 40 years or so. For example, the mathematical model predicts that long-lived Japanese women born in or after 1919 have at least a 50% chance of living to 122 or older, while long-lived Japanese women born in or after 1940 have a 50% chance of living to 130 .
  Of course, this mathematical model also has limitations. It does not explain the biological mechanism of aging, nor does it take into account that the advancement of modern medicine may extend human life.
