Frequently Asked Questions
How is health age estimated?
This tool starts from your real age and adds or removes years for BMI, resting heart rate, activity, smoking and sleep. It is an illustration, not a medical test.
Is this a medical diagnosis?
No. It gives general estimates from common formulas and cannot replace advice from a healthcare professional.
Why can results differ from other tools?
Different tools use different equations and category cut-offs. This one states the method it uses.
Can I change the inputs and recalculate?
Yes. Change any value and press Calculate. The result, the table and the explanation update straight away.
Note
Health age here is a simple educational estimate and not a diagnosis. For real health checks see a doctor.
