There are four basic types of blood—A, B, AB, and O—each with a positive and negative sub-type. O positive is the most common type, with AB negative being the least common. The letter designation of the blood type indicates which antigens are present in the blood cell. The antigen determines which blood types will join if donated. Types A, B, and AB have their titular antigens, and type O has no antigens. Thus, type O can be joined with any blood type, and is a universal donor.
Blood type also indicates which antibodies are present in the blood cell. The antibodies determine which blood cells the body being will reject. Type A rejects type B; type B rejects type A; and type O rejects both types A and B. Type AB contains no antibodies, so will accept any type of blood.

This has always got me interesting. So, what’s your blood type? Mine is B positive. I got to know my blood type back when I’ve done a blood test at Johor Specialists Hospital in 2005. I thank for that because if not, I wouldn’t even know what type my blood is lol :)
I’m only gonna write about Blood Type B and O xD why you ask? Because mine is B and my special friend is O hahaha
Type-B people are hunters. They have independent spirits with strong personalities. While they don't care what others think of them, they are extremely passionate about the things they hold dear. They can be shallow, lazy, and quite impatient.
People with blood type B are the most practical of the blood groups. They are specialists in what they do. When they start a project, they spend extra time understanding and trying to follow directions than others might. When they are doing something, all of their attention is focused on it. They tend to stick to a goal and follow it through to the end, even if it seems impossible. They tend to be less than cooperative, as they like to follow their own rules and their own ideas. They are individualists. B type people pay attention to their thoughts a little more than their feelings, and therefore can sometimes seem cold and serious.
People with blood type B are often considered more relaxed, freewheeling, and unconventional than other types, although not necessarily to an unacceptable degree. In anime, the genki, off-the-wall types are type B, along with any kind of well-intended character who's ruled by their impulses.
