"Mobile phones are hazardous for health"
Mobile phones are a boon to man-kind. Mobile phones are good and bad. Mobile phones have many advantages. We can communicate, get emails, get news online, watch videos , etc. Mobile phones can also be hazardous to health. When the phones are kept under the pillows it causes vibration and radiation, (depending on the size of the battery) which is very harmful for the brain and heart. These days, student's play games on mobile phones for a very long time. They keep the mobile phones very near to their eyes. This can be very harmful for the eyes. It can cause straining and boils. So, we should minimize the use of mobile phones and take care of our health.
