Is your chronological age different from you biological age? - study - The Jerusalem Post

While many things can affect our lifespan, scientists still don't understand the underlying processes that power aging.

In order to discover the cause of aging, researchers would need to watch biomarkers throughout a patient's lifetime which is impractical given the life expectancy of humans. .

“By studying the relationship between two outcomes of aging in the same individual, we can learn about the underlying aging processes that cause them,” notes Stroustrup.

The team found two partially independent aging processes that take place in nematodes simultaneously

While humans are more complex than nematodes and are more likely to have a greater number of biological ages, the study challenges the assumption that the underlying biology of aging has changed when one tries to revive a biomarker through interventions like exercise. 

Furthermore, this study calls into question the belief that animals have a single biological age that suggests their health by revealing how multiple independent aging processes can work together to cause different parts of the worm to age at different rates. 

“Biomarkers used to assess biological age can be changed without actually turning a ‘fast ager’ into ‘slow ager’,” Stroustrup concludes
