What's your number

It is often said age is just a number. 

I disagree. Age is a demographic parameter. While reacting to various circumstances, our age varies. 

While supporting our family, staying strong in the difficult time, or fighting for a cause, we behave like someone in their 40s. 

While giving someone a life lesson, we act like 60 year olds. 

While forgiving and forgetting, we have the innocence of 5 year old in our hearts. 

When showing affection to the ones we admire, we become teenagers. 

I believe age as a number is only for medical purposes and legal formalities. Otherwise, we will always be too young or too old.
