Your Longevity
Score

Method, limits and how to read your result

How it works

The score asks about ten areas of health and scores each from 0 to 10 against published guidelines and large studies, then averages them into a score out of 100. Activity questions follow the US Physical Activity Guidelines of 150 to 300 minutes of moderate activity and muscle-strengthening on 2 or more days a week (PAG 2018); step bands follow a meta-analysis in which benefits leveled off at about 6,000 to 8,000 steps for adults 60 and older (Paluch 2022); sleep follows the 7 to 9 hour range (Cappuccio 2010); alcohol bands follow the finding that mortality was lowest at or below about 100 g a week (Wood 2018); and social questions reflect evidence that stronger relationships are linked to longer survival (Holt-Lunstad 2010). Blood pressure and blood sugar categories follow the ACC/AHA and American Diabetes Association definitions.

Limits

Answers are self-reported, the ten areas are weighted equally, and the score has not been validated as a predictor of how long you will live. It does not score supplements, special diets such as time-restricted eating, or wearable metrics, because good trials have not shown that these improve health outcomes for most people. It is not a diagnosis.

How to read your result

Look at your lowest areas first; they show where changes are likely to matter most. Where a question asks about a test you have never had, the low score is a prompt to get it done, not a sign that something is wrong. Bring any concerns, especially about blood pressure, blood sugar, mood or sleep apnea, to your clinician.
