Do you know your blood type? 🅾️🅰️🅱️🆎 It can help you improve your health and even save your life in extreme situations. Also, it can say a lot about you personally! Japanese researchers have been studying blood types for decades and have found a surprising connection between a person’s character traits and blood group. We’re all well-aware that blood has different “types,” but what exactly does that mean? In a nutshell, blood type is based on two things: antibodies and antigens. An antibody is a protein produced by your blood’s plasma that helps your immune system fight different things that make you sick, like bacteria and viruses. Antigens, which are classified as A or B, can be different proteins, carbohydrates, and all sorts of complex biological compounds.
