Frequently asked questions

We aspire to provide the most accurate life expectancy calculator on the market. Our algorithm is based on the latest scientific research and is constantly updated to reflect the latest findings. However, it is important to remember that no calculator can predict the future with 100% accuracy. The results should be taken as an estimate, not a guarantee.

There are many factors that can affect your life expectancy, some of which are beyond your control. However, there are also many things you can do to improve your chances of living a long and healthy life. These include eating a healthy diet, exercising regularly, maintaining a healthy weight, not smoking, and limiting alcohol consumption.
