Suggestions
What is biological age?
It is a way of asking whether your body’s wear and risk profile looks more like someone older or younger than your birth date. It is not one number in medicine—different labs define it differently.
How is it calculated here?
We start at your chronological age and add or subtract years of estimated impact from BMI band, activity, sleep, diet, smoking, alcohol, and optional BP/cholesterol tiers. The output is a rough index for self-reflection.
How to reduce biological age?
Prioritize not smoking, regular movement, mostly whole foods, 7–9 hours sleep, and follow your clinician’s advice on blood pressure and lipids.
