Mobiles are not good as Nope they are no good and I am going to stick with this People stay up all night on them and don't have any rest
This is bad because people need a special amount of sleep to ensure they are healthy sorry to disagree but they are also not healthy. They cause radiation and the radiation causes cancer. People also shorten words and this is not helpful for students at school. Young people of today with mobile phones I don't think they are old enough, the age I think that need a mobile phone is 16 or 17. I also agree that they are bad because students use them to get answers for tests and that is wrong. This is my opinion.
