Lolz,this is a very good one and I think it as one time like that cause an argument me and a friend,but of all I want to say that it doesn't mean to me and I don't base or judge maturity base on old age ,as good as that is very important and can't be throw away too inife,but still doesn't mean that it is the criteria for maturity at all .

Just as I do tell people around me that grey hair or old age is not always wisdom,we have fool wit h gry hair out there
