BioAge
Younger, older, or right on schedule — a rough biomarker-based estimate.
Biological age looks at measurable fitness markers — resting heart rate, cardiovascular fitness, activity level — rather than the number of birthdays you've had, since two people the same chronological age can have very different underlying health trajectories.
This is a rough wellness indicator based on a handful of accessible inputs, not a clinical biological-age test (which typically uses blood biomarkers or DNA methylation) — useful for tracking your own trend over time rather than as a diagnosis.
