The use of cell phones in this era was just too ordinary. But looking at the phone too much and using it inappropriateness is very bad for your health. When you watch the phone too much it affects your eyesight. At night, we often have a habit of looking at the phone before going to bed such times that we often leave it on our head, affecting our chronic sleep loss. So let's use the cell phone in the most appropriate way.
