🧠⏳ Age. Biology. Truth.

A compelling Perspective in the New England Journal of Medicine challenges one of medicine's quiet assumptions: that age equals risk.

Two patients may share a birth year—but not a biology. From epigenetic clocks to physiological reserve, the evidence is clear: chronologic age is an imperfect proxy for clinical decision-making

⚠️ The consequence? Missed prevention in the young, withheld therapy in the old.

✨ The opportunity? A shift toward biologically grounded, precision care—where treatment aligns not with years lived, but with resilience retained.

The future of medicine may not ask "How old are you?"

…but rather, "How well are you aging?"
