Researchers have said that human beings can live up to 150 years if the usual stressors are eliminated. The ‘loss of resilience’ is the reason for death in the absence of other obvious reasons, like murder, cancer, or fatal accidents. As reported by Scientific American, three large groups from the US, UK, and Russia were a part of a study that analyzed the pace of aging. It was conducted by Gero, a Singapore-based company, in collaboration with Roswell Park Comprehensive Cancer Center in Buffalo, NY. The results of the study have been published in Nature Communications.
Resilience is the body’s capacity to recover quickly from difficulties. The study found that an 80-year-old individual might take three times longer to recover from stresses than a 40-year-old person. After a body goes through a stressful event like a disease, accident, etc., the recovery rate was found to deteriorate with age, and the time it takes to recover gets longer and longer. For a 40-year-old, healthy adult, the recovery rate is around two weeks, but it takes an 80-year-old adult around six weeks on average to recover.
According to a CNET report, the research estimates that human resilience is completely gone somewhere between the ages of 120 years to 150 years. This is observed even in people who do not have any major illnesses. The researchers believe that it was want to increase our life span, changes need to be made in our resilience factor and the aging process. Otherwise, the change will only be an ‘incremental increase in human longevity.’
“Aging in humans exhibits universal features common to complex systems operating on the brink of disintegration,” says Peter Fedichev, co-founder and CEO of Gero.
The researchers in this study created an indicator called the Dynamic Organism State Indicator (DOSI). By using data from wearable technology, they looked at data about blood cell counts and step counts. They found that CBC and step count fluctuations showed people’s recovery time when they experience stress. Recovery grew took longer as they grew older.
“The investigation shows that recovery rate is an important signature of aging that can guide the development of drugs to slow the process and extend healthspan,” said David Sinclair, Harvard Medical School professor of genetics.
Brian Kennedy, Distinguished Professor of Biochemistry and Physiology at National University Singapore, said, “The research will help to understand the limits of longevity and future anti-aging interventions. What’s even more important, the study may help to bridge the rising gap between the health- and life-span, which continues to widen in most developing countries.”
