i think it start from the mind,how u are cable to handle things

Yaaaaa...hmmmm
not so sure age has much to do with it

<~~~ hasn't matured yet

ok then at what age, 40,50,60 cus i gat some friends that reason like a kid at that ages

I would like to say that age does define maturity. But I have a 59 yr old neighbor who is emotionally 15 at the most.

I think it is defined by culture & religion & how people are raised. If you are told " When you are 13-15, 18, you are a man or woman... blah blah blah & this is what it means & this is what is expected.. blah blah blah " , then people will live up to it.

Here in the USA, we have many 30 yr olds living with their parents. Some left & returned, some never left.
People are leaving home, marrying & having children later & later.

Lots of reasons for that. Financial, etc.. But part of it may be inmaturity. Why leave home & be an independent, self reliant adult if dad pays the bills & mom washes your clothes ? And you can still do whatever you want ? No real responsibility, no real consequences laugh: * sarcasm *

Being mindful of consequences and taking responsibility for them.
Behaving in a manner consistent with normalized cultural expectations.


You can say everything regarding human behavior starts from the mind.


It's a good enough rule of thumb, judging maturity by age, or having expectations of behavior based on age.

Otherwise you're going to feel really insecure about where you stand, and not know what anyone around you can or will do at any given time unless every single individual human being you encounter you stop and get to know them well enough to trust them.
