Mark began to introduce the guest speaker to the listeners, but then stopped for a while. He had forgotten her name.

Barbara hid her valuable things when she went on vacation. When she came back, she couldn’t remember where she’d put them.

Perhaps you’ve had such experiences like these. Most people have. But most of them haven’t realized that they have a memory problem. Neither do they know a simple but important fact: Memory can be improved. If you just accept that, the following will show you how.

First, relax. If you are over worried about something, you’ll forget it. If you keep telling yourself that your memory is bad, your mind will come to believe it and you won’t remember things. When you forget something, don’t follow up with saying like “Oh, my god! I always forget things! ” Such words will have a bad result on you and your memory.

But relaxing isn’t enough. To improve your memory, you’ll need to take an active role. Like your body, your memory can be made strong through exercise. Look for opportunities to exercise your memory. For example, if you’re learning a language, try to actively remember a lot of new words.

If you don’t take notice of things actively, you won’t remember them. So, you can make pictures of what you see in your mind every day. For example, don’t just put your keys down! If you want to find them again, make a mind picture of the place where you’re putting them.

Your eyes 

    Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be more than 50 centimeters from the screen. Don’t forget to look away from it sometimes. This gives your eyes a rest.

When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on(反射)the screen. If the window is in front of you,the sun and the screen will both shine into your eyes.

Your hands and wrists(手腕)

Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something.

2) Keep your elbows(肘)as high as the keyboard.

3) Stop sometimes and exercise your hands, wrists and fingers in a different way.

Your back

Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you shouldn’t bend your back when you sit. The top part of the screen should be in front of your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel(平行)to the floor.
