Biologists from Russia, the United States and Singapore have created a test that can determine the overall condition of the body and physiological stability by blood analysis. It was reported on May 25 by the scientific journal Nature Communications.
The group of researchers proposed to use universal composite indicator DOSI (dynamic organism state indicator) for assessment of biological aging. According to their data, this indicator depends on the presence of diseases, age and lifestyle. The level of resistance was calculated by scientists with the help of data on physical activity, which they got from the sensors attached to the study participants.
According to biologists, the body becomes the least resilient by the age of 120-150. Thus, the article concludes that 150 years is the maximum theoretically possible human lifespan.
According to Fedichev, the scientists concluded that the age limit that leads to death “is an inherent biological property of the organism that is independent of stress factors and signifies the fundamental or absolute limit of human lifespan.”
In March 2019, scientists at the University of Sheffield in the United Kingdom said that one way to increase longevity could be to raise offspring together. Researchers found that female birds live longer if they are helped to raise their chicks, while single mothers age quickly.
