Could Your Blood Test Results Offer Clues to a Longer, Healthier Life?

The findings of the Swedish study contribute to a growing body of research suggesting that healthy aging is not determined by a single factor but by the long-term interaction of many biological processes.

Importantly, the researchers did not identify one “magic” blood test capable of predicting whether someone will live to 100. Instead, they observed that individuals who reached exceptional ages often shared a pattern of relatively stable metabolic health over many years.
