You can calculate your biological age using an online questionnaire like the Activ Age Calculator. This is as simple questionnaire which uses your actual age and then considers factors like your blood sugar level, cholesterol level, eating habits and lifestyle to calculate your biological age.

What is biological age and chronological age?

While chronological age refers to the actual amount of time a person has existed, biological age refers to epigenetic alteration and DNA methylation which express on how able and functioning she is and whether she has diseases related to old age.

How is chronological age and biological age determined?

Chronological age is measured in years; but biological age is assessed by a person’s physical and mental functions….And while genetics plays a significant role, other factors include:

### Can you be biologically younger than your age?

It is also determined by the length of one’s telomeres, which are caps at the ends of DNA strands. Telomeres affect how the body’s cells age. So, not only does a person with a younger biological age look younger, they are younger for all practical purposes (biologically).

What is meant by developmental age?

How do children of the same chronological age differ in biological age?

Children of the same chronological age can differ by several years in their level of biological maturation. Skeletal age refers to the maturity of the skeleton, which is determined by the degree of ossification of the bone structure. It takes into consideration how far bones have progressed, in size and density, toward maturity.

What does it mean if my biological age is less than normal?
