Frequently Asked Questions

What science actually says about life expectancy and longevity.

How accurate are life expectancy calculators?

They estimate based on large population studies and actuarial life tables — not your personal medical future. They're good at showing how habits shift the odds, but they can't predict any individual's outcome. Treat them as educational, not diagnostic.

What factors affect life expectancy the most?

Smoking is the single biggest reversible factor — heavy smoking costs 8–10 years. Next come regular exercise, a healthy diet, 7–8 hours of sleep, a healthy weight, limited alcohol, well-managed chronic conditions, and partly your genes.

How can I increase my life expectancy?

The highest-return moves: quit smoking, get 150 minutes of cardio a week, eat more vegetables and less processed food, sleep 7–8 hours, keep a healthy weight, and keep blood pressure, blood sugar, and cholesterol in range. Small, consistent changes compound over decades.

Is this quiz a medical diagnosis?

No. This quiz is for education and entertainment only. It uses population statistics and a simplified actuarial model — it is not medical advice and can't replace a doctor's diagnosis, checkup, or treatment plan.
