(37~39)    When you are taking a bus or the MRT, look at people around you. It’s common to see lots of them with their heads down, tapping on the screens of their tablets or texting on their smartphones. These people don’t want to let the grass grow under their feet, so they make good use of their time to keep connected with their friends. However, their bodies will pay a heavy price after doing that for a long time.    “Text-neck” is a health problem that is caused by the long-term use of your phone or tablet. To stay away from “text-neck,” follow the rules below. 1. Take breaks when you use your smartphone or tablet. Get up, walk around, drink some water, and do some exercise. Take a five-minute break for every fifteen minutes. 2. Use a tablet holder to keep your phone or tablet at eye level will reduce neck pain and other health problems. 3. Use a special APP called the Text Neck Indicator to keep your phone or tablet at a right angle. When the angle is right, a green light will be shown in the upper corner of your screen. But when the angle is not right, the light will turn red.  4. Listen to your body. If you feel pain in your neck, back, shoulders, hands, or head, don’t wait. Taking action now could prevent serious health problems in the future. If it really hurts, ask a doctor for help.
