If you spend a bit of time in Japan, someone will inevitably ask you, “What is your blood type?” This will come out of the blue, during a completely non-medical conversation, and will make you feel very very awkward for not knowing. The Japanese are not asking because they want to harvest your blood for weird experiments, but because in Japan, your blood type determines your personality type.

Let’s do a rundown of what each blood type means to your personality.

Type A: Conservative, introverted, reserved, patient, punctual, and perfectionist, but also obsessive, stubborn, self conscious, and uptight.

Type B: Creative and passionate. Animal loving. Optimistic and flexible. Individualist, but also forgetful, irresponsible, and self-centered.

Type AB: Cool, controlled, rational. Sociable and popular. Empathic, but also Aloof, critical, indecisive and unforgiving.

Type O: Ambitious, athletic, robust and self-confident. Natural leaders, but also arrogant, vain and insensitive. Ruthless

So, are these very vague and broad descriptions of personality types right about you and your blood type?
