Opinion on whether maturity is dependent on a persons age

No not true I know many people the are well over 50 and 60 and are nowhere near maturity 

I think maturity is not dependent on age.

I think the life choices and experiences you go through all affect your maturity. It all depends on what you've been through, some young people can through a lot and it can substitute what an adult has been through. It never depends on the age, just your experience or what you have been taught.

Um where is it at ? ?

Ifound this on google i hope it .
