A study led by the biotechnology company Gero predicts that the body can recover from stressful events for a maximum of 150 years, thus setting a "limit" for human lifespan.
However, researchers believe that they can exceed this limit. Researchers all over the world have been looking for a "source of youth" for years, a way to slow down or even stop aging. And, it could enable people to live decades or centuries longer than the current average.
But if the study's data turns out to be correct, all these efforts will stop by the year 150, no matter how effective the face transplant or blood transfusion procedures may be.
"If it does not target the loss of regenerative abilities, any type of medical intervention is destined to fail," argue the researchers in their study.
As part of the study, researchers analyzed blood samples from more than 500,000 people and took daily step data from another 4,500.
They specifically looked at how long it takes blood cells to return to normal levels after a person experiences some type of stress, such as an illness or injury.
They found that the average healthy 40-year-old could recover in 2 weeks, but 80-year-olds took an average of six weeks.
Even the healthiest people experience loss of elasticity as they age.
Maximum human lifespan: Based on this trend, the researchers predict a complete loss of "elasticity" between the ages of 120 and 150, meaning, they suggest, that no one will be able to live longer.
Gero's researchers believe that the fact that the maximum human life expectancy is not increasing at the same rate as the average life expectancy indicates that something inherent in our biology is at play.
