I don't think maturity has anything to do with age, granted alot of people that are old are matured but there are equally alot of young people that are quite matured as well.

Let me put it this way, maturity is a function of how sensible you are as a person, for old people being sensible stems from a life time of experiences which include ups and downs, successes and mistakes. As people get older they tend to get more matured because of all the things they've seen in life but this doesn't mean that this holds true for everyone.

I've met alot of old people who are just as childish as they were when they were younger, they haven't learned anything at all over the years. People like that are living proof that maturity doesn't necessarily come with old age.

I also have friends who have amazed me with the level of maturity that they've displayed oflver the years and most of them aren't even up to 30. Becoming mature is a decision you have to make on your own, you can either continue being ignorant or you can wisen up.
