Today, an increasing number of people are always looking at their mobile phones with their heads down. These people are called the "'Heads-down Tribe (低头族). Are you a heads-down tribe member? Heads-down tribe members now can be seen everywhere.

More and more traffic accidents are happening because more drivers use mobile phones when they are driving. In order to make drivers pay more attention to driving, some new traffic rules have been made. For example, people who use mobile phones while driving in Taiwan are fined (罚款). Car drivers and motorcyclists who break the traffic rule will be fined NT$ 3, 000 and NT$1, 000 respectively (分别地).

As we can see above, using mobile phones may cause accidents and even cost a lot of money. Also, more and more interesting and strange facts happen to the "Heads-down Tribe". Let's have a look at an interesting TV report. A man in America kept using his mobile phone on his way home. As a result, he knocked into a big lost bear. When he lifted his eves from the phone, he was so afraid that he turned around and ran away quickly. Another fact is that we can often see people in the restaurant eating face to face but looking at their own mobile phones. It's strange that they don't talk to the ones who sit opposite to them during the meal. Some of them even have fun communicating with others on the phone.

    Mobile phones are helpful and necessary tools for modern life. Are mobile phones good or bad? It depends on how people use them. Let's be "'healthy" users and try to be the "Heads--up Tribe".

    All people need to sleep. Sleeping is a restorative (恢复体力的) process that shapes better body functions and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.

    Your bedroom should be shaped to your taste and to allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom is also used as a place for your life and work, you will probably have a poor sleep. Bedrooms should be designed and used for sleep mainly. TVs, computers and other things should not be in your bedroom at all if possible.

    The regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time. Develop a regular exercise programme. Proper exercise and healthy food will help improve sleeping quality. However, avoid exercising 2 hours before sleeping, since this may keep your body exciting and make sleeping more difficult.

    A pre-bedtime rule will help you focus on sleep. You can try meditation (沉思), reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a special style. Do what is the best for you.

    Things such as room temperature, noise and light levels and even your bed itself can have a lot of effect on the quality of sleep that you experience. Cut down the annoying noises and lights. You are in your bedroom to sleep and not be distracted (干扰) by environment.
