All changes of character of the person can be divided into typical, natural and peculiar or atypical. Age changes undoubtedly can be referred to the first.
The first half of life
In process of growing the people get rid of traits of character which are peculiar to small children. It is accepted to refer to them capriciousness, irresponsibility, tearfulness, egocentricity and many other things. With age people gain positive or "adult" traits of character which are to a degree shown at all over time. It is possible to refer tolerance, rationality, responsibility, wisdom to these lines experience. By the way, accumulation of life experience in very big degree changes views of people of the events.
Twenty-year-old people live in the basic future, all their activity, thoughts of action are filled with plans which are more similar to pipe dreams. Most often in twenty years the people do not represent what difficulties they should meet therefore they look at the world very much, sometimes it is even excessively optimistic. Postponement of important things "for tomorrow", lack of tolerance and responsibility is characteristic of most of twenty-year-old people. But all this changes by thirty years.
At this age all thoughts of people are still directed in the future, but it not that distant and ephemeral future. In thirty years of people does not dream any more, and makes plans. To this age enough experience, ideas of life, as a rule, is accumulated what allows to look at the world with bigger confidence. Usually about thirty all traits of character become aggravated a little, positive and negative qualities become more expressed. By thirty years of people receives character which it deserved. In most cases after this age of any cardinal, serious changes does not occur if, of course, there are no serious emotional shocks which change all life.
Character in the period of a maturity
In the next two decades the people pass the boundary uniting for them both last, and future. Most often during this period (approximately by fifty years) to the forefront there are pragmatic traits of character facilitating life in the present, and here various idealistic properties which are connected with dreams and dreams, recede into the background. Aged people of sixty-seventy years of the future think much less, than of the past. Emergence of physical indispositions, falling of working capacity leads to emergence of nostalgia on the past. At this age it seems to people that in the past everything was better therefore sometimes to the forefront there are such traits of character as grumpiness, constant discontent with surrounding people. If the person at this age leads full life, communicates with friends, spends enough time with family, similar negative traits of character are shown to a lesser extent.
