It is easy for many people to catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why can't they find a cure for the common cold? The answer is easy. There are actually different cold viruses out there. You never know which one you will get, so there isn't a cure for each one.

When a virus attacks your body, your body works hard to get rid of it Blood rushes to your nose and causes a block in it. You feel terrible because you can't breathe well, but your body is actually eating the virus. Your temperature goes up and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting into your cells. You may feel very uncomfortable, but actually your wonderful body is doing everything it can to kill the cold.

Different people do different things to deal with colds. In the United States and some other countries, for example, people might have chicken soup to help them get over the cold. Some people take hot baths. Other people take medicine to stop different symptoms(症状)of colds.

There is one interesting thing to note一some scientists say taking medicine when you have a cold is actually bad for you. The virus stays in you longer because your body doesn't have a way to fight it and kill it Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this:

It takes about one week to get over a cold if you don't take medicine, but it takes only seven days to get over a cold if you take medicine.
