Abstract

A major goal of geroscience is to achieve the ability to predict the rate of aging using biomarkers for the purpose of extending lifespan and healthspan. Chronological aging is not a suitable marker as it does not capture the true status of age-related changes. So far, there is no biomarker or combination of biomarkers that has emerged even though some have shown promise. In this chapter, we summarize novel cellular, protein, and DNA-related biomarkers for biological aging that can be found specifically in the circulation “for the life of every living thing is in the blood”.
