Answer the following question: Read the article and select the best answer. Article: Travel is fun and exciting, but it's not if you get sick. You may think, "Not me, I won't get sick in my holiday." But, for many people, that is what happens. Of course you don't want to spend your holiday sick in bed. So what can you do to stay in good health? There are three things you should remember when you travel: relax, sleep, and eat well. A holiday must be a time for relaxing. But very often it is not. Think about what you do when you are a traveller. There are many places to visit: museums, shops, parks, churches. You may spend most days walking around these places. This can be very tiring. You may have a terrible headache after a few hours. If this is the way you feel, you should take a rest. Don't ask your body to do too much. A tired body means a weak body. And a weak body gets sick easily. So sit down for a few hours in a nice place. In good weather, look for a quiet park bench . Or you can stop at a cafe. You can learn a lot by watching people while you rest. Sleep is also important. If you want to stay healthy, you need to get enough sleep. You may have trouble sleeping at night when you travel. There may be too many noises in your hotel or the bed may be uncomfortable. If this is true, don't be afraid to change rooms or hotels. Or you may get enough sleep for another reason. You may want to stay out late at night. In many cities, the nightlife can be very exciting. Then you should plan to sleep for an hour during the day. The extra hour can make a big difference. Finally, if you want to stay healthy, you must eat the right kinds of foods but you need to be careful about how much you eat. Lots of food is not good for you. So, remember this, if you want to enjoy your holiday, take care of yourself. Give your body some rest. Get enough sleep and eat good, healthy food.
