🛠 How to Use the Lifespan Calculator (Step-by-Step)

Using the Lifespan Calculator is simple and takes less than a minute. Here’s how to do it:

  1. Enter Your Current Age
    Input your current age in years. This helps the calculator determine your remaining life expectancy based on other variables.

  3. Choose Your Lifestyle
    Options include:

📚 Helpful Info: What Influences Your Lifespan?

1. Gender Differences

Females generally outlive males by 5–7 years, on average. This may be due to genetics, lifestyle, and hormone-related protection from cardiovascular disease during reproductive years.

2. Exercise & Physical Activity

Being physically active boosts heart health, muscle strength, and brain function—factors that help increase lifespan.

3. Smoking

Smoking reduces life expectancy by about 10 years. Quitting can reverse many of the health risks over time.

4. Alcohol Use

Moderate drinking may have minimal impact, but heavy alcohol consumption can contribute to liver disease, cancer, and heart issues.
