Rate-of-Aging Test

How fast are you aging?

This Rate-of-Aging Calculator asks 14 questions to estimate how fast you are ageing, given your outlook and lifestyle.

The Biological Age Quiz (also on this website) will estimate your body's real age. It estimates your biological age in years. Together, these two tests give you an estimate of your life expectancy and the likelihood of your having a healthy fully functional body in your later years.
