I think 18 years are considered to be mature in terms of Age.But again there is a possibility that someone gets the gift of emotional maturity before 18.

It has more to do with the individual than with age. Many eighteen year-olds are more mature emotionally than many "adults" in their thirties.

I'm presuming you mean other than physically mature...such as intellectually and emotionally. YES, a 13 year CAN be capable of making rational and emotionally sound decisions. However, for most young adults, it's still a growing process. H*ll, for many ADULTS it's either an underdeveloped or totally absent process, from what I've seen! At any rate, it's fairly relative. Some people simply think and behave more mature than others. By the time most people hit their teen years, their core values and beliefs are pretty much set. What they really lack is the intellectual knowledge base and experience that time will bring them as they grow further. This additional time allows them to affirm these values and beliefs on their own as they apply themselves to the real world outside their parents reach. Oh yeah...and let's not forget those hormones. The teen years are rife with hormonal changes. Probably more so for the boys than the girls as girls start a little sooner than boys. But still, those years are important as they allow the body time to finish growing physically and for the mind to learn to cope with the effects of those hormonal changes on an emotional level. Most especially the emotions dealing with "lust" and "love".

mature in what sense, sexually mentally physically all people are different and girls generally asre much more advanced at 13.then again some of us never grow up

Consider wine. Some wines are bottled, but experts know that the wine will not mature for years. At the point of maturation, the wine has reached a level of acceptability; further aging will only modify that by degree. If we consider a 13 year old in our society, we have reason to doubt that they have at their command the mental, emotional, physical and spiritual equipment to be considered mature adults. Some young people might find themselves in the position of having to care for their brothers and sisters due to the absence of parents. Doing so, others may remark on their maturity. That is an indication that our situation can force us towards mature behavior when we really are not ready for it. I am convinced that daily, people of long years are passing away, never having matured in the sense that many have felt important.

Yes, some of us were forced to mature past our age.

No, a thirteen year old can't really be mature.

If it's a 13 year old piece of cheese, yes.

Some can. Everybody is different. There are some immature 25 year-olds out in the world.

YUP! ME! :D Lol. Never mind. Can't? If u ask me, it depends on the individual. My 7 yr old cousin still acts and looks like a 4 yr old. I think he has ADD...

That would really depend on the level of responsibility and at what rate a 13 year old was given. And of course how well they managed the responsibility. Maturity comes from a mix of life experiences and basic human knowledge, It then turns into wisdom through the success of making discussions. Not all humans become mature, as some behave as children their entire lives. But then being serious all the time does not make you mature but only appear as such. Can 13 year olds become mature? Yes to a certain degree in many ways but maturity is not measured in years but in the way you behave during situations. As you grow older you can become more mature because you have lived and seen more and have taken on more responsibility.
