All six domains are at the top. Keep what works and check again in 3 months.
How it works.
- Answer one question per screen; use Back if you want to change an answer.

- Take one of the three suggestions and save the card to compare in 8 to 10 weeks.
What the score measures, and what it does not.
The Longevity Habits Score adds up twelve answers about your everyday routines: six domains, two questions each, 3 points per question, 36 raw points scaled to 100. It measures habits, not biology. It is not a biological age, not a risk calculation and not a prediction of how long you will live. Two people with the same score can be in very different health, because genes, medical history and luck are not among the questions. What the score does show is where your week already matches what the long-term studies point to, and where it does not yet.
Where the six domains come from.
Each domain follows a public guideline or a large body of evidence. Movement uses the WHO recommendation of 150 to 300 minutes of moderate activity a week plus muscle-strengthening work on 2 days; the guide on daily steps translates that into distances. Food leans on the NHS target of 5 portions of vegetables and fruit a day, about 400 grams, and on the 30 grams of fibre a day that most adults miss by 10 grams or more. Sleep uses the 7 to 9 hours that the National Sleep Foundation names for adults and the minimum of 7 hours from the American Academy of Sleep Medicine, and it adds regularity, because a wake time that shifts by 2 hours or more works against the body clock. Connection follows the Holt-Lunstad meta-analysis of 148 studies, in which people with stronger social ties had a 50 percent higher chance of survival; the guide on social connection and health goes through the numbers. Stress and purpose draws on what the longest-lived regions share: a reason to get up and daily ways to settle. Environment combines the 120 minutes a week in nature from the 2019 study of nearly 20,000 people by White and colleagues with tobacco, the single largest modifiable risk in mortality statistics.
How to read a low score.
A score under 40 is a starting point, not a verdict. The scale is built so that one change moves it: an extra 20 minute walk on 5 days a week, or one more portion of vegetables a day, is worth about 3 points on the 100 scale. Pick the weakest domain from the radar chart, take one of the three suggestions, and give it 8 to 10 weeks before you test again. The tool keeps only your last score in your browser so you can compare. Whether better habits turn into more good years is the question the guide on healthspan versus lifespan explores, and the answer there is measured in years free of illness, not in points.
Frequently asked.
Is this a biological age test?
No. The score adds up twelve answers about habits: minutes of movement, portions of vegetables, hours of sleep, people you can call. It says nothing about your cells, your blood values or your genes, and it does not predict lifespan.
How is the score calculated?
Each question has four answers worth 0, 1, 2 or 3 points, so the twelve questions give 36 raw points. That total is scaled to 100. Each of the six domains has two questions, so a domain can reach 6 points, which is what the radar chart and the bars show.
What should I do with a low score?
Treat it as a map, not a mark. The three suggestions come from your two weakest domains; pick one, keep it for 8 to 10 weeks and then answer the twelve questions again. One raw point is worth about 3 points on the 100 scale, so a single habit moves the number.
Does the tool store my answers?
It stores only your last score, as one number in your own browser, so the page can show it next time. Your individual answers are not kept and nothing is sent to a server.
Why does the tool ask about tobacco but not about weight?
Tobacco is a habit, and in mortality statistics it is the single largest modifiable risk. Weight is an outcome rather than a habit, so it does not belong in a habits score; the waist to height ratio tool covers that measure separately.
Why are there two questions on sleep instead of one?
Hours matter, but so does regularity. A bedtime and wake time that shift by 2 hours or more between weekdays and weekends works against the body clock, even when the total reaches 7 to 9 hours.

The Longevity Habits Score is a self-check of everyday routines. It is not a biological age, not a diagnosis and not a prediction of lifespan, and it cannot see symptoms, medication or medical history. This page is for general information and does not replace medical advice.
