so I am type AB

I never knew what my blood type was until I was 14, checking my blood was part of the physical check-up. I am type AB positive, which didn't come to a surprise since my mom is a B, my dad is an A.

However, I did receive some weird looks when I disclosed that I am type AB. My friends told me that type ABs are selfish, sneaky and weird, I suppose being weird can be subjective, but I didn't think that I was that selfish nor sneaky.

When I was in biology class, I learnt that people with AB blood can receive blood from any type in tranfusion, but AB blood can only be accepted by people with AB blood. So, to put it another way, AB takes blood from everyone, but only gives blood to AB. I suppose this is where the selfish thingie come from.

When I was donating blood a few years ago, I asked the nurse, since AB blood can only be accepted by AB and O blood can be accepted by everyone, does that mean my blood is less desirable? She said no, because the plasma from AB blood can only be donated to people with AB blood, while O blood people can take plasma from any blood type. Another thing, she added, AB is only about 4% of the population in the world, while O and A take about 75%. I guess that is where the sneaky thing come from, we are a rare breed!

So I have done further research, the blood type personality research was done in the early 20th century, when German Nazi used it to justified that they are a superior race. (more A and O, while more B in Jews and Asian) Then Japanese catched on, thought the finding will breed better soliders, then the craze faded in the 1930s as its unscientific basis became evident. However, in 1970s, some writer/journalist named Masahiko Nomi, who had no medical background, wrote books on blood type and personality. In the book, A is common in Japan, O is prime minister material (60% of Japanese prime ministers are Os), B makes good cooks while, AB is often considered the least desirable type. Nomi became famous, and so did the theory.

According to Nomi:

A - law-abiding, conservative, introverted, reserved, patient, punctual, perfectionist, good with plants, obsessive, stubborn, self conscious, and uptight.

O - outgoing, passionate, and individualistic, ambitious, athletic, robust and self-confident, natural leaders, arrogant, vain, insensitive and ruthless.

B - carefree and cheerful, creative and passionate, animal loving, optimistic, flexible, individualist, forgetful, irresponsible, and self-centered.

AB - serious, cool, controlled, rational, sociable, popular, empathic, aloof, critical, indecisive and unforgiving.

I know it is probably not right to divide people into four groups and determine their personalities that way. If there are only four types of people in the world, it would be a very boring place. Plus, I found myself with traits from other blood type as well. I wonder what if I combine horoscope, blood type, chinese horoscope all together, would that be an accurate description of my personality?

oh, and please, now you know where the theory came from, please stop discriminate people by blood types (esp. type AB), try discriminating them by the way they treat small animals. :)
