Biological age testing
Estimating how worn the body is from blood markers, epigenetics or telomeres
A number meant to say how old the body is rather than how many birthdays it has had. The methods differ a lot: epigenetic clocks read DNA methylation, some scores are built from routine blood markers such as A1C, blood pressure and inflammation, others count telomere length or blood metabolites. They disagree with each other, sometimes by years, which is why researchers who use them tend to run several and take an average instead of trusting one. Consumer kits are widely sold and there is still no agreed standard.

Asked which test he rates, he names Morgan Levine's score, the one built from everyday blood markers such as A1C and blood pressure. Where several tests disagree, he suggests averaging them instead of keeping the kindest result.
