to break it down...

<18=boy/girl
18+=man/woman


but maturity has to do with being able to handle situation responsibly generally.

therefore, a 40year old person who can't behave responsibly will be regarded as immature.

Alright,

This makes sense.

RESPONSIBILITY!!!!
a 10 years old kid who caters for his siblings is in every sense a matured man in comparison to a 40 years old who lives only for himself.

The word again is RESPONSIBILTY. the size and spread of ur responsibility is the measure of ur maturity.

Wow, amazing answer.

A boy becomes a man when he starts taking care of his responsibilities, while a girl becomes a woman when she get married and birth a SON.

Really?

Interesting.

Matured mind...driven by experience

Wow, I like this answer.

Having read the very commendable comments so far,

Can we say maturity has to do with responsibility and not just by age?

Again, is there more to maturity than just being responsible?

Some say a person is a man or woman because he/she has come of age. Is this really true?

I am curious to know your take on this matter. Let's discuss people. Who knows, we can learn a thing or two or more
