How the Longevity Quiz works
Gender-specific questions. After selecting “Woman” or “Man”, the quiz shows only the relevant set of questions, each aligned with the statistically supported factors (relationship style, purpose, social connection, stress relief, and wealth/autonomy).
Scoring logic. Your answers are scored against the longevity evidence and converted into a projected healthy lifespan. The better your alignment with the longevity-promoting patterns for your gender, the more healthy years. Your age range + region calibrate the projection to the right survival curve — they never add or subtract points.
Instant feedback. After submitting you'll see your projected age, a personalised message, and a breakdown per factor — strengths in green, areas to improve in yellow or red — plus the evidence behind your score.
Clean, responsive interface. Card-style layout for desktop and mobile. The gender toggle updates question visibility smoothly, and you must answer every question before seeing results.
Your age range — never exact, for accurate calibration
Your age adds no points — combined with your region, it calibrates the projection to the right survival curve: a 70-year-old is measured against her own life stage, and a Kenyan is not measured against Malaysian life expectancy.
