The personality of type B blood changes over time

　　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 unpredictable prophet".

　　As time changes, how will the personalities of people with type B blood change?

　　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.
