Five rules for a healthy life
Thanks to better health care, most people are living healthier and longer lives. It's even thought that in the future more and more people will celebrate their hundredth birthdays. Here are five rules for a healthy life.
⒈Get off the sofa!
Sure, it's comfortable to sit on the sofa and watch TV. But doctors say you should get off the sofa. 要保持健康，你每天至少应走10000步。In the past, people's jobs required more physical effort. They often had to walk for miles every day. When farmers were working, they were keeping fit at the same time. Think about it: Do you get the same amount of exercise today as they did in the past?
⒉Eat healthy food!
It's important to eat food that is fresh and natural, for example, fruit and vegetables. Fast food is not healthy. You should only have it once in a while. Eating too much of the wrong food will harm your health.
⒊Rest while you can!
When we were babies, we slept for much of the night. Teenagers do not need as much sleep as babies, but it's important for you to get about eight hours' sleep a night. At weekends, you've got more time, so use it not just for your friends, but for rest too.
⒋Don't worry. Be happy!
Many people believe that happiness is important for our general health. Sometimes it is not easy to be a teenager because of the difficulties of school, exams or friendships. If you're worried about something, talk to your parents or your teacher.
⒌Say no to smoking!
Yes, you knew I was going to say this! It's so important. Smoking is not cool. It is dangerous. It harms nearly every part of your body. Think about how your family and friends will feel, and think about what it will do to your health.
If you eat too much of the wrong food, your health will be harmed.
