Look at your personality changes by blood type

'

Personality is not fixed, it changes constantly with time, place, and situation. You cannot easily determine its nature with a single sentence or a phenomenon. Even so, through the relationship of blood type, we can still roughly predict the change of a person's personality, and achieve "an unknown prophet". 
    For people of the four blood types, how will their personalities change over time?

Blood type O human

    O type personality changes the most with time. Among young people who have just started to work, O-type people are generally honest, loyal and docile to their superiors, and are easy to gain leadership favors. After entering adulthood and having some experience at work, they began to actively express their opinions and express themselves, sometimes appearing tough.

People with blood type A

    Type A people are just the opposite of Type O people. When they were young, they were resolute and strong everywhere. After entering the society, they began to restrain themselves and showed a steady and modest attitude as they grew older. They tended to become cautious people who did not want to overexpress themselves. However, generally in old age, they become more stubborn.

 

Blood type B human

    The age change of Type B people has little effect on temperament. However, sometimes it turns from being cautious to being outspoken, but this is not a change in personality, but because of familiarity with the surrounding people and environment. Since the personality of this kind of person rarely changes from childhood to old, relatively speaking, it makes people feel that they live younger and younger.

People with blood type AB

    People with type AB have dramatic personality changes with age. Early childhood and adolescence were very cognizant of birth and did not want to contact people. As they grow older, they become a different kind of person: positively speaking, good at giving opinions, having a wide range of communication, being generous to people, and good at communicating. However, perhaps because of overconfidence, they become arrogant when they are complacent with their achievements and merits.
