Imagine you could remember everything that ever happened to you. The detail(细节)of every book you have ever read. Every moment in class you have ever taken. A perfect memory sounds like a wish come true, doesn't it?

But as the old saying goes, Be careful what you wish for. Believe it or not, there are some people in the world who have near perfect memories of their experiences. They remember almost every detail about almost every day of their lives. People with this ability have a "highly superior autobiographical memory(超级自传体记忆)," or HSAM.

If you are asked this evening to describe the events of your day in as much as detail as possible, you will probably do pretty well. But if I ask you to provide details about what you did on March 3, 2012, do you know what day of the week it was? What did you eat for lunch? Was it cold that day? You would have no idea where to even begin.

A person with HSAM would be able to provide all those details for almost any day of his or her life. In addition to(除了)every great moment they remember, they also remember each time they were embarrassed(难堪)or deeply sad. The negative(消极的)events replay in their minds in equal detail as the great moments. Sometimes,forgetting isn’t such a bad thing.

In fact, for most of us, forgetting is a natural part of how our brains function(运转). If we don't need to remember something or try to make an effort to remember it, the information fades away(消逝)and is lost. But for those people with HSAM, the problem is that they are unable to forget. All of their experiences, even the most unimportant, remain clear to them all the time.

Research has shown that the brains of people with HSAM do not simply function differently than other brains; their brains are structurally different. By studying the brains of people with HSAM, scientists may be able to find ways of helping others have better memories—not perfect memories with an inability to forget, but better memories.

Don’t Disrespect Others

More than 70 years ago, a young man traveled far away to take an entrance exam for a famous music school. During the exam, he tried his best, but the examiner didn’t enroll (录取) him.

The young man had no money, so he could only make a living by playing the violin on the street. He played so well that a lot of people stopped to listen and put money into his violin case.

A hoodlum (流氓) dropped some money at the young man’s feet. The young man bent down to pick up the money, then handed it to the hoodlum and said, “Sir, your money dropped on the ground.”

The hoodlum took the money, threw it at the young man’s feet again and said, “This money has been yours, so you must take it!”

The young man deeply bowed to him and said, “Sir, thank you for your support! When you dropped your money, I picked it up for you. Now my money is on the ground, may I trouble you to pick it up for me?”

The hoodlum was surprised. Finally, he picked up the money, put it into the young man’s violin case and left in shame.

The examiner who had been quietly watching the young man among other onlookers decided to give him a second chance. He brought the young man back to the school and enrolled him in the end.

The young man became a famous musician later.
