Maturity often means many things. For me when I use the word maturity I relate it to mental and emotional maturity. People often associate it with physical maturity, however they don't always go hand in hand. Whilst you can expect a child to be immature, once they reach their teens most start to develop mental and emotional maturity, some not till their 20's.

What do I mean by this defition of maturity? Well others have eluded to it already, it means a sense of self responsibility, an awareness of ones self and the fact that your actions can have an effect on others and a reasonable ability to determine right by wrong.

Immaturity is not fart jokes. Immaturity is not laughing at someone falling over. Alot of people associate things like these, so called "childish" acts as immature, I disagree as it speaks little of their capacity to be responsible for their actions. Someone mentioned wisdom earlier, I think wisdom is an important part of maturity, but wisdom alone does not determine maturity. Telling a fart joke only really speaks of your sense of humour and not maturity.

Hehe, I am having a hard time pinning down what I feel is maturity...to use an umbrella term, I feel a massive part of it is moral autonomy, the ability to act and make decisions with some moral basis. This encompasses a whole lot of things that I think are relevant. It is mixed in with taking responsibility for your own behaviour.
