🧮 Example: Calculating Your Life Expectancy
Here’s an example to show how the calculator works in practice:
Example Scenario:
- Age: 40
- Gender: Female
- Lifestyle: Healthy
Calculation:
- Base expectancy for females: 81 years
- Healthy lifestyle adds +5 years → Total: 86 years
- Years remaining: 86 – 40 = 46 years
Result Shown:
Estimated Life Expectancy: 86 years
Approx. 46 years remaining.
This simple result can serve as a wake-up call or reassurance — and either way, it’s useful information.

📚 Additional Insights on Life Expectancy
While this calculator provides a quick estimate, real-life longevity can be influenced by numerous factors beyond age, gender, and lifestyle. Here are a few:

Family history plays a key role. Longevity can run in families due to inherited traits.
Medical History
Chronic conditions such as diabetes, hypertension, or heart disease can shorten lifespan.
Socioeconomic Factors
Income, education, and access to healthcare services can influence health and life expectancy.
Geographic Location
Where you live matters — people in areas with high pollution, poor healthcare infrastructure, or limited access to healthy food often live shorter lives.
