Frequently Asked Questions
How accurate are life expectancy calculations?
Life expectancy calculators provide statistical estimates based on population data. They're useful for understanding risk factors and making lifestyle decisions, but individual lifespans can vary significantly due to genetics, accidents, and other unpredictable factors.
What has the biggest impact on life expectancy?
Smoking has the largest negative impact (up to 10 years), while regular exercise, maintaining healthy weight, and avoiding chronic diseases have the most positive impacts. Social connections and mental health are also significant factors.
Can lifestyle changes really extend life expectancy?
Yes, research shows that healthy lifestyle choices can add 10+ years to life expectancy. The Blue Zones (areas with exceptional longevity) demonstrate that lifestyle factors like diet, exercise, social connections, and purpose significantly impact lifespan.
How does gender affect life expectancy?
Women typically live 4-5 years longer than men on average. This is due to biological factors (hormones, genetics) and lifestyle differences (risk-taking behavior, healthcare utilization, occupational hazards).
What role does family history play?
Genetics account for about 20-30% of longevity factors. Strong family longevity patterns can add 2-3 years, while family history of early mortality may reduce life expectancy. However, lifestyle factors can often overcome genetic predispositions.
How do I improve my health score?
Focus on modifiable factors: quit smoking, exercise regularly, maintain healthy weight, manage stress, get quality sleep, limit alcohol, and manage chronic conditions. Even small improvements in multiple areas can significantly impact your health score.
