An article published in the journal Nature has sparked intense debate among peers and scientists for its theme: age limit of humans. It is problematic, according to scholars from the field, because the study published by Jan Vijg, Ph.D., and two other peers from the Albert Einstein College of Medicine (New York), claims that the maximum age limit of humans would be 115 years.
Controversy Regarding the Maximum Age Limit Sparks Intense Debate
The core idea of the article revolves around the idea that humans and the age limit would be of 115 years, as opposed to the previous longest living people (a French citizen who lived a 122-year life).
One researcher, S. Jay Olshansky, School of Public Health University of Illinois at Chicago wrote, in an email to Gizmodo, that
“The authors of the rebuttals quibble about how to deal with the mathematics of small numbers at extreme old age”.
He then continues to argument that the problem is that the conclusion would be wrong. He says that the data that is available indicates not only that the assertion that the age limit would be 115 years, but that the oldest people alive are getting even older.
Rudi Westendorp, professor of Healthy Ageing at the University of Copenhagen, says that, in his opinion, Vijg focuses on a small group of people that achieve extreme longevity. However, this is wrong, because, he says, a larger pool of people that have reached an advanced old age indicates that the life expectancy of people doesn’t increase, but it increases.
Another researcher, Nick Brown from the University Medical Center Groningen in the Netherlands, said that he and his team, along four other teams, went over the Nature paper all over again and found plentiful errors. First of all, the existence of the age limit at 115 years is dependent on the age and death date of the oldest person known in history. That person was Jeanne Louise Calment (French citizen), who lived 122 years. In other analyses, there has been an increase in the number of people who have passed the age of 100 years, which makes it likely, according to the respective analyses, that there will be more people to live beyond the age limit of 115 or 122 years.
Among others, there is one more problem that envisages the use of statistic tools. Breaking the data into individual years of death of respective people is an arbitrary decision, as is the division of time itself an arbitrary concept, says one study.
A core of ideas regarding the age limit study was published in the Dutch magazine NRC.
