How Old Are You Really

The birthday candles say one number; the epigenetic clock says another — and mailing saliva or blood to learn which has become the longevity movement's favourite reckoning.

Inside this volume

Fifty first-person accounts open their results: the younger-than-expected who felt vindicated, the older-than-expected who overhauled sleep, drink and training, retests that rewarded the work, and retests that contradicted the first test entirely. Writers dig into which clocks measure what, the variance that humbles precision claims, subscription retesting economics, and the physicians who translate 'biological age' into the plainer language of modifiable risk.

Who it's for

For anyone tempted by an epigenetic age test, holding a result and deciding what it deserves, or auditing the clocks before paying one.
