What is your blood type?

One of the weirder things I've experienced in Korea so far has been the "What is your blood type?" conversation. To Koreans, asking someone their blood type is like asking what your sign is, or when your birthday is. It's completely normal and not at all creepy like it would be if someone you just met asked you in the US. I myself have been asked this at least 10 times already by people I just met (including my co-teacher's husband on the car ride to my homestay). Koreans believe that they can tell your personality based on your blood type, and I think they take it kind of seriously. Here is an explanation of the different blood type personalities I found online. I'm type B, which I actually think suits me almost to a T.

KOREAN BLOOD TYPE PERSONALITIES:
Blood Type A:
Positive Traits: Conservative, introverted, reserved, patient, punctual and inclined to be perfectionists.
Worst Traits: Obsessive, stubborn, self conscious and uptight.
Referred as ‘farmers’ in some descriptions, Type A’s are said to be considerate of others and loyal to a fault. Although they apparently don’t find it easy to like, they can also be secretive and reluctant to share their feelings. Apparently they don’t hold their liquor well, either.

Blood Type B:
Best Traits: Animal-loving, creative, flexible, individualistic, optimistic and passionate.
Worst Traits: Forgetful, irresponsible and self-centered.
Referred to as ‘hunters’, Type B’s have very independent natures and tend not to be concerned about what other people think of them. Although often described as shallow and lazy, they can be quite passionate about the things they hold dear. Patience is not their strong suit either.
Type B men have acquired a very negative reputation in Korea and are not considered by many to be good husband material. Often described as ‘players’, they are perceived as being selfish and mercurial, quick to anger and not terribly reliable. That said, their bad boy image makes them very attractive to women, but not for the long term. (Type B women do not share in this bad rep, for some unexplained reason).

Blood Type AB:
Best Traits: Cool, controlled, empathic, introverted and rational.
Worst Traits: Aloof, critical, indecisive and unforgiving.
Referred to as ‘humanists’, Type AB’s are said to be controlled more by their heads, than by their hearts. They are rational, good with money, but unpredictable. Although inclined to be distant, they prefer harmony and as such, work well with mediators. Some consider them two-faced, and therefore untrustworthy.

Blood Type O:
Best Traits: Ambitious, athletic, robust and self-confident.
Worst Traits: Arrogant, insensitive, ruthless and vain.
Referred to as ‘warriors’, Type O’s are viewed as natural leaders and are often, also, natural athletes. They tend to be outgoing, expressive and passionate, but can also bore others to death with their obsessive drive for success coupled with their absolute convictions that they are winners. This certainty that they will always win explains why they aren’t afraid to take risks or gamble. They have a strong physical presence and are unlikely to ever be overlooked.

In typical Korean Konglish style, as a reward for completing English camp, my students were given small notepads by my co-teacher with the phrase "What is your blood type?" written in big letters on the front. Only in Korea...
