Practical Example

Let’s take a real-life example to understand how the calculator works:

A 35-year-old individual enters the following details:

• Gender: Male
• Smoking: Yes
• Exercise: Moderate
• BMI: Overweight
• Alcohol: Moderate

Result Output:

• Estimated Lifespan: 74 Years
• Remaining Years: 39 Years
