What is the Pace of Aging Test?

A free questionnaire-based test that scores lifestyle factors — sleep, training, nutrition, stress — to estimate how fast you are aging relative to the chronological average.

Yes — the test is completely free and requires no registration.

How accurate is the result?

The result is an estimate grounded in published lifestyle geroscience research. For medically precise figures we recommend epigenetic blood tests (Horvath, GrimAge, DunedinPACE).

How is this different from the Face Age test?

Face Age analyses a photo to estimate visible biological age. Pace of Aging asks about lifestyle and estimates how fast you are aging. The two tests measure different dimensions and complement each other.

Calculate Your Biological Age

A science-based self-assessment: estimate your biological age and see how fast you're aging based on lifestyle (your pace of aging). An estimate only, not a medical diagnosis.
