Given these statistics, you can expect the record for the longest life span to grow as well. Nearly a quarter of a century after Clement’s death, it is known that no one matched his 122 years, let alone exceeded it. The closest was an American named Sarah Knaus, who died two years after Calment at the age of 119. The oldest living person is 118-year-old Kane Tana, who lives in Fukuoka, Faponia. Very few go through it after 115. (Several researchers have even questioned whether Clement actually lived as long as he claims that many accept his registration as legal because of the weight of the biographical evidence.)
As the world’s population approaches eight billion, science is finding more and more promising ways in the laboratory to slow or eliminate aging, and the question of the possible limits of human longevity is more pressing than ever. When their work is studied in detail, it is clear that scientists of longevity have a wide range of subtle perspectives on the future of mankind. Historically, however, according to some researchers, somewhat bluntly, their views have been divided into two broad camps, which some journalists-researchers call pessimistic-optimistic. The members of the first group view the life span as a candle that can burn only for so long. They generally think that we are fast approaching or have already reached the end of our lives, that we will not soon see anyone greater than Kalmant.
In contrast, optimists view life expectancy as a supreme, perhaps even infinite, elastic band. They predict significant gains in life expectancy around the world, increase the number of extraordinarily long-lived people, and, ultimately, the superfluous people who survive on Clement, bringing the record to 125, 150, 200 և more. Although unresolved, the long-running debate has already given rise to a much deeper understanding of what defines life limits, the interventions that can one day prolong it significantly.
Theoretical boundaries Human life has plagued scientists and philosophers for thousands of years, but for much of history their discussions have been based primarily on personal observations. In 1825, however, the British actuary Benjamin Gompertz published a new mathematical model of mortality that showed that the risk of death increased exponentially with age. If that risk continued to accelerate throughout life, people would eventually reach a point where they had virtually no chance of surviving next year. In other words, they would bring an effective limit to life expectancy.
Instead, Gompertz noted that as people get older, the risk of death increases. “The limit of a possible life span is a subject that will probably never be determined,” he wrote, “even if it exists.” Since then, using new data և more sophisticated mathematics, scientists around the world have found further evidence of accelerating mortality, followed by mortality rates not only in humans but also in many other species, including rats, mice, crabs, nematodes, and fruit flies. :
In 2016, a particularly provocative study in a prestigious research journal Nature: He obviously assumed that the authors had found the essence of human life. Ian Weig, a geneticist at Albert Einstein College of Medicine, “two colleagues analyzed decades-old mortality data from several countries” and concluded that although the highest death rate in these countries rose rapidly between the 1970s and 1990s, it failed to rise from that time. , 9 years. The depth of human life seemed to have reached its limit. Although some individuals, such as Jean-Anna Calment, may have reached a staggering age, they did not stand out for their continued life expectancy.
