Was watching running man when i noticed that they kept on talking about blood types.
Googled it and here it is haha.
Blood Type A - Tend to be cooperative, sensitive, clever, passionate and smart. Often bottling up anxiety in order to get along with others, they may hold in their emotions until they explode. Many are tense, impatient and unable to sleep well. While they are capable of leadership positions, they may not take them because the stress is not good for their tightly wired systems. They are perfectionists to say the least. This quality shows up in their perfecting electronics like TV's and also less expensive more efficient cars that were originally created here in the US.
Blood Type B - Blood type B individuals tend to be balanced: thoughtful like A's and yet ambitious like O's. They are empathetic, easily understanding others' points of view, yet often hesitating to challenge or confront. Chameleon-like and flexible, they make good friends.
Peter D'Adamo found that While their immunity is strong, they are more prone to slow-growing viral infections like lupus, MS and chronic fatigue.
They may also have problems with hypoglycemia and blood sugar, especially if they eat the wrong foods.
Blood Type AB - Tend to be very charming and popular. They don't sweat the small stuff and can be seen as spiritual and even at times a bit "flaky". Only about 2 - 5% of the population are blood type AB. There is never a dull moment in a AB's life, so if you find one for a friend, consider yourself lucky! Like blood type A's, AB's react to stress poorly. They are stronger and more active than type A's, but need to pay attention to stress levels so that they don't compromise their immunity. Sometimes it is difficult to be an AB. AB's don't like to fit in anyone else's "boxes". If they feel too confined, they'll break out of that box and do things their own way.
Blood Type O - Tend to be loners or leaders and are intuitive, focused, self-reliant and daring. They handle stress better than other blood types and have strong immune systems, a well developed physique and a physically active nature. Blood type O's tend to have sluggish blood flow and feel better with vigorous exercise for about an hour each day.
