What Is Biological Age?

This article is a placeholder. The full piece is being written and will replace this text in a later milestone.

Chronological age counts birthdays. Biological age tries to describe something more useful: how well your body appears to be holding up.

The finished article will cover:

  • what biological age actually refers to, in plain language
  • the signals researchers use to estimate it
  • why two people of the same chronological age can differ
  • what a biological age estimate can and cannot tell you

In the meantime, the FAQ answers the most common questions about how this calculator produces its estimate.
