Can You Lower Your Biological Age?

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

This question attracts a great deal of confident marketing and rather less careful evidence. The finished article will try to be useful rather than dramatic.

It will cover:

• what changing a biological age estimate really means
• the habits most consistently associated with better outcomes
• how long changes plausibly take to show up
• claims that are not supported by the evidence

In the meantime, the FAQ explains how this calculator treats change over time.
