In 1901,Karl Landsteiner,an Austrian scientist,discovered that there are four types of blood.These four blood types were named A,B,AB and O.People have one of these four types.

Blood type O is the most common around the world.Blood type A is the second most common,and type AB is the least common.If people with type A blood are given type B blood,or people with type B blood are given type A blood,they will probably die.

In 1927,a Japanese doctor,Furukawa Takeji,carried out research and came up with the idea that people with different blood types also had different personalities.He said that people with type A blood are usually calm and serious;people with type B blood are curious,cheerful and outgoing;people with type O blood are generous and honest;those with type AB blood are often caring,original and careful.

More recently,a doctor in the United States wrote a book that links blood types and what people eat.For example,his book suggests people with type O blood should eat more meat and less bread.A diet for people with type A blood includes more vegetables.His book,Eat Right for Your Type,has been a hit with people who want to lose weight.However,Dr.Peter D'Adamo believes that eating food that matches a person's blood type can do more than help them lose weight.He thinks it w ill make the person healthier in other ways,too.

76.The Austrian scientist,Karl Landsteiner found that there are ________________________.

77.People with type B blood will be in danger if they are given ________________.

78. The Japanese doctor found people with type B blood are usually ________________________________.
