Scenario:

  • Age: 40
  • Gender: Male
  • Smoker: No
  • Exercise: Regular (3+ days/week)
  • Diet: Good
  • Family History: Yes

Calculation Breakdown:

  • Base life expectancy for males: 78 years
  • Not a smoker: no deduction
  • Regular exercise: +2 years
  • Good diet: +2 years

Frequently Asked Questions (FAQs)

1. How accurate is the life expectancy calculator?

It’s an estimate based on statistical averages and lifestyle data. It does not predict actual lifespan.

2. Does smoking really reduce life expectancy by 8 years?

On average, yes. Numerous studies show that long-term smokers lose between 8–10 years of life compared to non-smokers.

3. Why is family history included?

Longevity often runs in families due to both genetics and lifestyle patterns.

4. What if I select “Other” for gender?

The tool assigns a neutral base (80 years) when “Other” is selected to reflect average life expectancy across all genders.

5. Can I increase my life expectancy?

Yes. Quitting smoking, eating well, and regular exercise can improve your health and increase your projected lifespan.

6. Is a poor diet really that harmful?

A consistently poor diet can lead to chronic diseases and shorten lifespan by several years.

7. Does the calculator store my data?

No. All calculations are done locally on your device. Your data is not saved or shared.

8. Why does exercise increase life expectancy?

Exercise improves cardiovascular health, reduces stress, and helps prevent many age-related conditions.

9. Can children or teens use this calculator?

It is designed for adults, ideally those over 18. Results for children may not be reliable.

No adjustments are made for unknown history to keep results unbiased.

It starts with a gender-based average and adjusts based on your inputs using logic-based modifiers.

13. Can this be used for health insurance planning?

Not officially, but it can offer useful insights into your risk profile.

14. Is diet more important than exercise?

Both are critical, but a poor diet can negate many benefits of exercise over the long term.

15. How often should I use this tool?

Use it whenever you make lifestyle changes or as part of annual wellness tracking.

16. What if I lie or exaggerate in my answers?

The results will reflect the data you input, so dishonest responses won’t yield accurate predictions.

Not in the current version, but future iterations may include more factors.

18. What should I do with the results?

Use them as a conversation starter with your doctor or to reassess lifestyle choices.
