Have you ever forgotten where your socks are when you wake up in the morning? Can you remember what you ate for lunch a week ago? You may think that being forgetful is not a good thing. But now you should be thankful.

Scientists from University of Toronto found that forgetting actually is a key part of learning. Getting rid of (除去) unnecessary information can help our brains work better.

What kind of information is unnecessary? Scientists say that this may have something to do with the environment you live in.

In an environment that is always changing, our brains may require us to remember less. For example, a supermarket cashier (收銀員) meets many people every day and will probably only remember them for a short time. But a designer (設(shè)計(jì)師) who often meets his or her clients (客戶) will remember longer.

“That’s because our brains keep making new neurons (神經(jīng)元) from stem cells (干細(xì)胞). ”said Paul Frankland, a professor at the University of Toronto.

There is a special area in our brains called hippocampus (海馬體). It is important for us to learn and remember. When new neurons fit in the hippocampus, they renew our old memories. This could explain why you forget so much information about the time when you were very young.

However, being forgetful is not always good. When you don’t have enough sleep, you may have a hard time remembering new information. Sleep helps the brain store and keep new facts and information. Matthew Walker from the University of California told the Huffington Post.
