- Compared with the SSA average
Keep the number in perspective. This model combines studies and anchors a chosen reference profile to the SSA population average. It has not been calibrated or validated for individual predictions. Tenths of a year show small model changes, not that level of scientific certainty.
See what shaped your estimate
A 2× mortality hazard does not mean 50% fewer years. We recompute survival year by year. Cross-study factors are multiplied under an independence assumption; overlapping effects can make the result too extreme.
Which answers change the number?
19 of 24 questions feed the number: age and table, height and weight, current or former cigarette smoking, alcohol quantity, produce, whole grains, nuts, unprocessed red meat, processed meat, fish, aerobic activity, strength activity, sitting hours, sleep duration, blood-pressure category, diabetes, and specified diagnoses.
Each question can change the estimate within the model’s supported comparisons; not every small change, unknown answer or diagnosis has a coefficient. Study bands can give the same result. Multiple modeled diagnoses remain outside scope.
Five questions guide care advice: cholesterol, family heart history, family cancer history, recommended screening, and healthcare access. Their broad answers do not support universal all-cause lifespan multipliers. See the evidence for every question.
The reference profile and assumptions
The SSA population rate is used as the anchor for a reference profile: never smoked, BMI 22.5–<25, 150–299 activity minutes weekly, no strength training, 4 sitting hours daily, 7 hours of sleep, blood pressure below 140/90 without medication, no alcohol or modeled diagnosis, and 5 produce servings daily. Added food comparisons each use zero intake as reference.
This mixed profile is a mathematical comparison, not a recommended diet or a measured average U.S. profile. The SSA population is actually a mixture of profiles. This shortcut is not population calibration, so the result demonstrates direction rather than predicting your lifespan.

Your next steps
Pick a change that fits your life. These suggestions respond to your answers; their order is not a medical risk ranking.
Some cards show years reported in research. These are study comparisons, not extra years calculated for you. Benefits overlap, so don’t add the figures together or to your estimate.
The science, the math, and the limits
Baseline and health scenario
The official SSA baseline is unchanged. The health scenario adjusts annual death hazards using sourced hazard ratios and explicitly approximated risk ratios, then applies diagnosis coefficients to two-year death odds. It recomputes the survival curve and remaining years rather than subtracting fixed year penalties. Ages display one decimal to reveal smaller changes; this is display precision, not scientific accuracy.
This is an educational adaptation combining studies, not a reproduction of their full models. It assumes persistent effects, independent lifestyle and food multipliers, and a reference profile anchored to population mortality. These assumptions are not validated. Multiple diagnoses, unsupported BMI, and ages outside 25–79 do not receive a scenario.
We add your whole-year age to the SSA’s published remaining life expectancy at that age. This is a period estimate: it holds 2023 mortality rates constant and does not predict future medical advances.
The displayed span contains the middle 80% of death ages in the table, conditional on being alive at your age. It is a population spread, not a confidence interval for you. Survival probabilities come from the table’s annual death probabilities; percentiles assume deaths are spread evenly within each year.
How to read the years on advice cards
Years shown are published study comparisons, with the behavior, comparison group, and study age context stated. Observational findings do not prove that making a change will add those years. A model also depends on assumptions.
Benefits overlap and cannot be added together. Activity research uses modeled median survival age, while the SSA baseline is a mean. Neither is a personal guarantee. Your health answers change the separate directional scenario; the official SSA number stays unchanged.
Full disclaimer and study references
SSA publishes male and female tables. The selection is a statistical reference, not a statement about identity; these tables cannot account for intersex variations or gender-affirming treatment. Both are available to compare.

Scope
For adults ages 18–100 using a U.S. population reference. Guidance is educational, not diagnosis or treatment. Diagnosed conditions need a clinician’s assessment. Non-U.S. populations may have substantially different mortality patterns.
Data and guidance checked October 2, 2026. This is not an official SSA or American Heart Association tool. The directional model is an educational adaptation, not an official or clinically validated prediction tool.
