Question 1: How old are you?

About This Longevity Quiz

This quiz estimates your life expectancy using research-backed lifestyle and health signals. It is an educational tool. It does not diagnose disease or replace medical care.

Your result reflects patterns seen in large studies, not a promise about any single person. Use it to spot habits worth improving, then talk to your clinician if you want a personalized plan.

What Your Result Means

The score estimates life expectancy, which is the average number of years people with similar profiles tend to live. It is different from healthy life expectancy (HALE), which focuses on years in good health. In the United States, life expectancy in 2023 was 78.4 years. Your daily choices still matter. Many risk factors are modifiable.

How The Estimate Is Calculated

The quiz weighs multiple domains that are linked to longevity in population studies:

• Smoking status, past or current. Quitting reduces disease risk and can add years of life (source: CDC).
• Physical activity minutes and muscle-strengthening days per week. Adults benefit from at least 150 minutes of moderate activity and 2 days of strength work (source:  CDC guidelines).
• Sleep duration and regularity. Most adults need 7 or more hours of sleep. Very short or very long sleep is linked with higher mortality in cohort studies (source:  CDC, systematic review).
• Weight and central adiposity. Body mass and waist size both matter. Larger waists are associated with higher cardiometabolic risk (source: CDC).
• Alcohol use. Any level carries a health risk, including cancer. Lower intake reduces risk (source: WHO factsheet).
• Strength and mobility. Low handgrip strength and poor chair-stand performance are risk markers in older adults. Common cutoffs for low grip strength are <27 kg in men and <16 kg in women (EWGSOP2).
• Social connection. Stronger social ties are associated with better survival (source: meta-analysis).
• Preventive care and medication adherence, when relevant.

Each domain contributes a portion of the score. Protective habits raise the estimate. High-risk patterns lower it. The model is simplified on purpose so you can act on it.

Methodology and Limitations

• The estimate draws on guideline thresholds and cohort evidence. Examples include CDC activity and sleep guidance, WHO alcohol risk summaries, and EWGSOP2 muscle-strength cutoffs.
• Associations are population averages. Genetics, access to care, and comorbidities can shift individual risk.
• Self-reported answers can be inaccurate. If you are unsure about a value, use your best recent measurement and retake the quiz later.
• This is not medical advice. For symptoms or specific concerns, see a clinician.

What To Do With Your Result

Pick one change you can keep. Consistency matters more than intensity. These steps are realistic for most people:

• Move most days. Aim for 30 minutes of brisk walking, 5 days a week, and add two short strength sessions (what counts).
• Protect your sleep window. Target 7 to 9 hours for adults and keep a steady schedule (CDC sleep basics).
• Reduce alcohol. Fewer drinks reduce lifetime risk (WHO Europe).
• Work on social health. Regular contact with friends or community groups helps both mind and body.
• Measure your waist at the level of your navel and track progress (how waist size relates to risk).
• If you smoke, make a quit plan today. Support increases success (CDC quit resources).
