After entering society, as they grow older and accumulate social experience, they begin to restrain their emotions, show a steady and humble attitude, and tend to become cautious who are unwilling to overexpress themselves. Type A people are very stubborn in old age.

Type B

　　Most of them have a naive and romantic infancy. As they grow older, they gradually divide into two tendencies: outspoken and not good at socializing. Type B people have little change in their personalities since they were young, and relatively speaking, people feel that they live younger and younger.

Type O

　　They are more docile when they are young, but as they grow older, they will actively show strong self-assertion and self-expression, and even become very courageous people. O-type people have the biggest changes from childhood to old age. They are usually the docile teenagers and the tough ones when they grow old.

Type AB

　　Most people are afraid of strangers when they are young and are very closed, but when they grow up they are good at making friends and socializing widely. Type AB people are easily complacent because they are overconfident, and they feel very arrogant in old age.
