Researchers looked at “pace of aging” in three large cohorts in the U.S., the U.K. and Russia.
To evaluate deviations from stable health, they assessed changes in blood cell counts and the daily number of steps taken.
For both blood cell and step counts, the pattern was the same: as age increased, some drove a predictable and incremental decline.
Using this predictable pace of decline to determine when resilience would disappear entirely, they found a range of 120 to 150 years.
With age, the body’s response could increasingly range far from a stable normal, requiring more time for recovery.
Blood pressure and blood cell counts have a known healthy range, however, whereas step counts are highly personal.
"...the fact that both sources paint exactly the same future, suggests that this pace-of-aging component is real," - Peter Fedichev, study co-author.
