The difference may 41 in their ability to foresee the consequences of their actions, according to a recent study.Brad Bushman, a psychologist at Ohio State University, and his colleagues asked nearly 500 volunteers to play a simple game. The subjects, an even mix of women and men, believed they were competing 42 an opponent to press a button as quickly as possible.

Half the participants then received enough alcohol mixed with orange juice to make them legally 50 , and the other half received a drink with a very 51 amount of alcohol in it.

When drunk, 55 , their aggressiveness was off the charts. "They are 56 the most aggressive people in the study," Bushman says.The good news is this 57 can be changed.
