Longevity Metrics That Matter: Expert Insights on Biological Age
Biological age promises a more honest answer than your birth certificate. But which metric should you actually track? For anyone who has been monitoring wellness for a few years, the standard markers—resting heart rate, blood pressure, lipid panel—start to feel like a report card that never changes.

The problem is that the market is already crowded with competing tests, each backed by different assumptions. This guide compares the main approaches, gives you criteria to evaluate them, and helps you build a monitoring plan that avoids the traps of data overload and false precision. Who Should Choose a Biological Age Metric and Why Now The decision to track biological age is not for everyone.
