How is your memory? Remembering things is an important function of our brain. If you think about it, there is so much we have to remember - from where we left our car keys to how we walk. However, do you often find you are forgetful?
Mernory allows the brain to store and recall information when needed. Our short-term memory can hold a small amount of information for a short time, while our long-term memory can hold a large amount of information for a long timc. Our memory is amazing, but why do we still forget things?
It's possible we don't always store information in our memory casily, maybe because we are in a rush or we consider it not important at the timc. When we do storc information, we often make connections with other things, which helps us recall it later. If you don't have these connections, then it can be casier to forget.
But sometimes even our short-term memory can let us down. Have you ever gone into a room to get something only to forget what you wanted when you got there? This is called "The Doorway Effect". Writing for the BBC Future website, scientist Tom Stafford explains that this happens because we change both the physical and mental（心理的）environments， moving to a different room and thinking about different things.
Besides, if you have a mind like this, it could be because you have too much on your mind. But we do need to keep our memory good by continually using it, espccially when our brains begin to become smaller and our memory starts to get worse after the age of 50.
However, as Luis Villazon says, "Forgetting is not always a bad thing! It would be too tiring if we remembered everything of the world around us. " There is always something that we can keep in mind!
