Your health score

of 100

Answer the 97 habits below to see your Health Score, and which habit is your biggest drag and your biggest lift.

How this score is built

Nothing here is a new study number. Every habit’s points are the same published figures the other What Matters pages print, converted onto one ruler and added up. A habit on several pages (exercise: lifespan years, dementia risk, brain age, sleep quality) becomes one pill whose levels carry the sum, and every answer is saved under its usual quiz key.

The midpoint is 50: a typical adult, every answer at its reference (the life model’s population-average answer, or the study’s reference group). Each answered habit moves it by its points. Unanswered habits and answers with no number add nothing.

Three co-equal pillars. Every figure counts on exactly one of Longevity, Mental age or Body age, and each pillar’s parts are scaled by its weight so the three carry a peer share of the total swing. The hero shows your points on each.

PillarShareWhat counts on it
Longevity×135.1%205.2 pts · 53 habitsYears of life expectancy for every habit that is not a physical or mood habit, plus every dementia risk and every mortality risk, for any habit but a mood one.lifespan · dementia · sleep and lifespan
Mental age×134.4%200.8 pts · 35 habitsEvery brain-age year, and every published figure behind a mood or mental-health habit, whichever page it comes from. No mood-only number is invented.cognitive age · the mood habits’ lifespan, dementia and sleep figures
Body age×1.530.5%178.1 pts · 34 habitsThe physical habits’ years of life expectancy (exercise, strength, sitting, diet, weight, blood pressure, cholesterol, blood sugar, fibre, sleep hours and apnea) and every sleep quality figure. No body-age number is invented.lifespan (physical habits) · sleep quality
PagePointsWhy this ruler
Lifespan2 per year of life expectancyThe life model’s own option deltas; current smoking (−8.7 y) is worth about 17 points. Longevity for most habits, Body age (×1.5) for the physical ones, Mental age for the mood ones.
Dementia10 per +100% relative riskLifetime risk is about one in five, so +100% is roughly 20 absolute points of risk; depression (+120%) weighs 12. Longevity, or Mental age for a mood habit.
Sleep and lifespan3 per +100% mortality riskLongevity. Lifespan years already carry most of sleep’s effect on mortality, so a third of dementia’s ruler.
Cognitive age1 per brain-age yearMental age. Doubled from the first cut so cognitive fitness is a clear half of the pillar next to mood; frequent video games (−13.7 y) is worth about 14 points.
Sleep quality0.2 per Total Sleep Score pointBody age (×1.5). Each meter’s sub-score change, blended 0.40 / 0.35 / 0.25 as that score does; treating apnea is worth about 3.6.

Mood and mental health inside Mental age: 12.9% of the swing

No mood ruler is invented. The 6 habits whose question is about mood or mental health count exactly as much as the published figures behind them, 75.2 points of swing between them, 12.9% of every habit’s swing added together, all of it on the Mental age pillar next to the brain-age years (1 per brain-year).

  1. #2Mental health treatment+26.6 pts · 4.6% of the swing
  2. #10Low mood+17.2 pts · 3% of the swing
  3. #18Sense of purpose+10.1 pts · 1.7% of the swing
  4. #19Stress+9.4 pts · 1.6% of the swing
  5. #22A daily relaxation practice+8.8 pts · 1.5% of the swing
  6. #51Worry and rumination+3.1 pts · 0.5% of the swing

Where the numbers come from: the life model’s mood, treatment, purpose and stress years; the Lancet Commission’s depression risk [2] and sense of purpose [45] on the dementia page; chronic stress [46]; rumination brain-age years [70]; the relaxation-practice sleep figures.

The ruler is linear. Above the midpoint, 100 means every habit at its best answer (+227.9 net); below it, 0 means every habit at its worst (−352.1 net). Your net is placed in proportion (score = 50 + 50 × net ÷ 227.9 above the line, 50 + 50 × net ÷ 352.1 below), so every point of net is worth the same wherever you sit. Attention span is not in the score: its page stays, but a same-day alertness index is not a health outcome of its own and its figures were mostly conversions of sleep and caffeine habits already counted.

Ranking and weights: pills are ordered by each habit’s swing, its best published answer minus its worst, in points; its weight is that swing as a share of every habit’s swing added together. A star (*) marks a level with a projected or converted part on its own page; a habit whose every level is such a projection is left out of the ranking. Age, sex, genes, family history, conditions, medicines and circumstances are left out on purpose: this ranks what you can change.

Age, sex, ethnicity, genes and family history sit outside this score on purpose: it ranks habits, the things you can change. Conditions, medicines and circumstances with a pill on another page (head injury, APOE4, migraine, chronic pain, hormone therapy, beta-blockers, shift work, education) are left out here for the same reason.

The years we cite — every option delta and its calibration.

Answer the 97 factors above to see which ones raise your own risk, which sit at the reference, and which the studies have no number for.

Health Score points versus each habit’s reference (a typical adult’s answer), above the line better, below it worse: 2 points per year of life expectancy, 10 per +100% dementia risk, 3 per +100% mortality risk, 1 per brain-age year, 0.2 per Total Sleep Score point, Body age parts ×1.5 so the three pillars are peers (* marks a projected or converted part).
