r we really mature???

People say often that now i came to a maturity level. How can we say that we are mature??? Is it the way we think make us mature??? Or Its the way we do prove us a mature person???

These all came to my mind when i was sitting with my friends and suddenly started discussing what exactly makes us mature. Is it the thing which came automatically when we cross 18??? Or its the brain which makes us mature. On discussion some people said that maturity is the thing which states how we think at some instance. Maturity defines on the level of thinking but what i think is if i know that what we think is right and not following that will push us and others in some problem and still we don't take any action so which kind of mature we are? I think Exposure is the thing which makes us mature....... exposure to the world, exposure to the knowledge, and many more. The maturity depends on thinking and reaction both. Exposure gives us a real world touch where we came to know about the different scenes of life and what is the right approach to pass it. By experience only (it may be ours or others) we are able to take right decision at each step of our life. And taking and following right decisions in each level of our life defines our maturity level.

As said:

"Life is a boolean tree, its totally depends on you to make it right or wrong by taking decisions at each node between yes or no"

Why?

Umm

1. A good source of timepass
2. Nice way to keep in touch
3. A place to share and recall good and bad times
4. A prospective old age delight :D
