4．In 1901，an Austrian scientist discovered that there are four types of blood．He named them 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 blood type AB is the least common．
In 1927，a Japanese doctor found that people with different blood types have different personalities （性格），too．He said that people with type A blood are usually calm and serious；
people with type B blood are cheerful and outgoing； people with type O blood are generous and honest； while those with type AB blood are often caring and talented．
More recently，a doctor in the United States wrote a book that connects blood types with what people eat．The 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 will make the person healthier in other ways，too．
