There are four types of blood: A,B, AB or 0 and also a Rh factor which can be either positive or negative for each blood type. The notorious Nazi doctor Otto Rehe was the reason why the effect of blood types on human health was not studied for a long time.

Women who have this blood type can become pregnant even in older age since they have a larger ovarian reserve. People with blood type A have predisposition to alcoholism and Obsessive Compulsive disorder too.
