The strongest baseline driver for remaining life expectancy.
The strongest baseline driver for remaining life expectancy.
Used only for population-level actuarial baseline differences.
Location captures healthcare access, safety, pollution, income, and population mortality patterns.
Tobacco exposure is one of the largest modifiable longevity factors.
Use your best current estimate; body composition can refine this later.
Count brisk walking, cycling, sport, gym, active commuting, or comparable effort.
Mediterranean-style, minimally processed, high-fiber diets generally score higher.
Long-term sleep regularity and duration influence metabolic and cardiovascular risk.
Use treated or untreated status if you know it.
Includes diagnosed heart disease, cancer, diabetes, COPD, kidney disease, or stroke.
Average weekly pattern.
Work, commuting, and leisure combined.
Phone/watch estimate is enough.
Resistance training, calisthenics, loaded work, or equivalent.

If waist is more than half height, risk is generally higher.

Regular supportive contact with friends, family, partner, or community.
How often stress feels persistent or hard to recover from.
Mood, anxiety, purpose, and ability to function day to day.

Restorative sleep, insomnia, snoring, or suspected apnea.
Daily sugar-sweetened beverages.
Legumes, whole grains, vegetables, fruits, nuts, and seeds.
Especially important with aging and strength maintenance.
If prescribed medication, how reliably do you take it?
Routine adult vaccinations appropriate for your age and location.
Screens close to bed can reduce sleep quality.
Movement, daylight, recovery, and mental health proxy.
Housing and work protection from extreme temperatures.
Balance, frailty, hazards, or previous falls.
Untreated sensory loss affects accidents, cognition, and social connection.
Learning, reading, complex work, languages, music, games, or creative projects.
Clubs, volunteering, faith groups, local projects, or mutual aid.
Pets, family, children, or others who add movement and social rhythm.
General expectation that problems can be worked through.
How easy it is to access healthy food near home/work.
Useful for deciding what CTA should eventually offer.
The calculator prioritizes the variables that most often move a population-level life expectancy estimate: age, location, smoking, activity, diet, sleep, blood pressure, chronic disease, body composition, social connection, stress, and preventive care.
Results are directional and should not replace clinical judgment. The best product path is to turn the CTA into a personalized improvement plan, partner offer, screening path, or paid longevity guide.
