Do you know what the aging clock is?
In the paper of Mildred Min, Caitlin Egli and Raja Sivamani M.D., M.S., A.P. you can learn about these predictive models of biological age derived from age-related changes, such as epigenetic changes, blood biomarkers, and, more recently, the microbiome.
Recent studies have shown that human microbiomes may predict aging.
In this narrative review, they discuss how the gut and skin microbiomes influence aging clocks as well as clarify the distinction between chronological and biological age.
