Playing Tetris after a traumatic event can help eliminate bad memories. A study of car wreck survivors found that those who played Tetris in the ER had 62% fewer bad memories than those who just wrote down what happened. Their memories also faded more quickly, so it’s believed that Tetris both distracts you from taking pity on yourself, and interferes with the way long-term memories are stored. Source Source 2
