Is it possible to live up to 150 years? Yes, according to a new scientific study, but our bodies would not be able to go beyond this age.
Man has always been in search of the so-called elixir of life, but up to what age could we really live in the absence of serious diseases? Science finally has an answer. According to a recent study, in fact, the maximum limit of human life is 150 years.
This threshold was calculated by an international team of researchers, who also made use of artificial intelligence to investigate how long our organism could resist (at least potentially). The results of the study were published in the journal Nature Communication.

The results of the research
To uncover new details about longevity, the scientists took a blood sample from over 70 people aged up to 85 from the UK, Russia and the US to observe the short-term change in white blood cell status and of red blood cells. Subsequently, they then collected various information that was included in a single parameter that takes the name of “indicator of the dynamic state of organisms (DOSI) and indicates the human being's ability to maintain homeostasis, that is, to resist decay. This indicator basically measures a person's biological age.
The changes in the participants' DOSI values allowed for predicting who would contract age-related diseases and how this varied from person to person, modeling the loss of resilience over time.These calculations predicted that in all cases, independently from health status or genetics, resilience would cease to function completely at 150 years, placing a theoretical limit on the length of human life.
According to this study, the complete loss of resilience of the human organism therefore occurs between 120 and 150 years. Exceeded this absolute limit, our body would no longer be able to regenerate and continue to live. Beyond this threshold, therefore, death inevitably occurs.
But of course the research in question has limitations and does not take into account some factors (such as the discovery of new drugs and medical advances), which will have to be examined by future investigations. In any case, as pointed out by the authors of the study, the latter "will help to understand the limits of longevity and future anti-aging interventions" and may serve "to bridge the growing gap between health and life span, which continues to widen in the most of the developing countries ".
