To calculate someone’s life expectancy, scientists look for molecular changes that take place in cells. This approach determines mortality risk by focusing on a person’s rate of aging (biological age) as distinct from their chronological age.
But a novel approach has emerged that takes information from routine blood tests carried out at a doctor’s office. Proponents of the new strategy suggest these readily-available measurements can be used as a practical, accurate and easy-to-interpret “lifespan calculator.”
Unlike genetic tests, which provide information that’s engraved in stone, the blood data used to establish biological age can be modified by lifestyle changes to increase an […]
