Your calendar age is just the number of years since you were born. Your body age \u2014 also called biological or physiological age \u2014 tells a more interesting story. It reflects how old your body actually behaves based on key health markers like BMI, activity level, lifestyle habits, and existing health conditions. Two people can both be 45 years old, but one might have a body age of 38 (aging slower than average) while the other has a body age of 52 (aging faster). Our Body Age Calculator<\/a> estimates your body’s true age in seconds.<\/p>\n\n\n\n
