Common questions
How accurate are life expectancy calculators?
Life expectancy calculators provide rough estimates based on population averages and known risk factors. They cannot account for genetics, accidents, or rare diseases. Use them as motivational tools to identify modifiable risk factors, not as medical predictions.
What are the biggest factors that shorten life?
The biggest life-shortening factors are smoking (reduces life expectancy by 10+ years), obesity (3-7 years), heavy alcohol use (3-5 years), sedentary lifestyle (3-5 years), and chronic stress. Most of these are modifiable through lifestyle changes.
How can I add years to my life?
The most evidence-backed strategies are: never smoking (or quitting), regular exercise (150+ minutes per week), maintaining a healthy BMI, moderate or no alcohol, a diet rich in vegetables and whole foods, strong social connections, and adequate sleep.
What does longevity research say?
Blue Zone research shows that the longest-lived populations share common traits: regular low-intensity movement, plant-heavy diets, strong social bonds, sense of purpose, and moderate calorie intake. Emerging research on caloric restriction and NAD+ precursors shows promise but is not yet conclusive.
