Chronological age is a term used to indicate the number of years a person has lived. However, there are alternative words that can be used to denote the same thing. For example, you could say "actual age," "calendar age," or "live age" to refer to chronological age. Another option would be to use the term "biological age" to indicate the bodily changes that occur with age. Alternatively, you could opt for "physical age" to describe a person's overall physical condition related to age. "Mental age" refers to a person's cognitive development relative to their chronological age. Lastly, "real age" can be used to highlight a person's true age, rather than how old they may appear or feel.
