🔍 Practical Example

Let’s walk through an example:

Profile:

  • Gender: Female
  • Age: 40
  • Smoking: No
  • Exercise: Moderate (3–5 times/week)
  • Diet: Good
  • Alcohol: Moderate

Calculation Breakdown:

  • Base Female Life Expectancy: 85 years
  • No smoking: No deduction
  • Moderate alcohol: −1 year
  • Moderate exercise: +3 years
  • Good diet: +3 years

Estimated Life Expectancy = 85 − 1 + 3 + 3 = 90 years

Since the user is currently 40, the calculator confirms a reasonable life expectancy of 90 years.

❓ Frequently Asked Questions (FAQs)

1. Is this tool medically accurate?

No. It offers an estimate based on average data and cannot replace professional health advice or diagnosis.

2. Why does gender affect life expectancy?

Statistically, women live longer due to a mix of biological and lifestyle factors. This tool reflects those general trends.

3. Can I use this if I have a medical condition?

Yes, but the result won’t reflect specific medical conditions. It’s a lifestyle-based tool, not a clinical calculator.

4. Does quitting smoking improve my life expectancy in the tool?

Yes. Selecting “No” for smoking removes the −8 year penalty, simulating the benefits of quitting.

5. What counts as ‘moderate’ alcohol consumption?

Generally, 1 drink per day for women and 2 for men is considered moderate.

6. What defines a ‘Good’ diet?

A good diet includes fruits, vegetables, whole grains, lean proteins, and limited processed foods or sugars.

More frequent exercise adds more years:

  • Light: +1 year

The calculator balances your inputs. You’ll gain points for exercise, but a poor diet won’t help your longevity score.
