What is the science behind the new bioage test?

Specifically, Epigee looks at the methylation patterns at various CpG sites that are known to correlate with chronological age. By analyzing these patterns, they can estimate an individual's biological age, which may differ from their actual chronological age. They are using 2 cpG and all the approaches described in detail in the article https://www.frontiersin.org/journals/genetics/articles/10.3389/fgene.2021.772298/full
