Biological Aging Terms

Essential terminology for understanding biological age measurement, epigenetic clocks, and the pace of aging.

Measurement

A measure of how fast a person is biologically aging, expressed as years of biological aging per calendar year.

An estimate of how old a person's body is physiologically, based on biomarkers rather than date of birth.

A set of measurable biological indicators used to assess organ function, disease risk, and aging status.

The distinction between calendar age (years since birth) and functional age (physiological state of the body).

An algorithm that estimates biological age or aging rate from DNA methylation patterns at specific CpG sites.

A third-generation epigenetic clock measuring the rate of biological aging, developed by Duke University researchers.

A daily metric synthesizing sleep, recovery, and activity data from wearables to indicate physiological preparedness.

The process of connecting consumer health devices (Oura, Whoop, Garmin, Apple Watch) to provide continuous physiological data.

PaceSovereign's proprietary metric that synthesizes biomarker data, wearable inputs, and epigenetic measurements into a single aging rate indicator.

The systematic process of improving biological function and reducing the rate of aging through data-driven interventions.
