Certainly cell phones affect people dramatically when Driving and texting (likely to kill them); but, they also affect or cause other damages when they are not used properly, for example: families without effective communication between them because their members are prisoners of cell phones, social gatherings or "dead" parties because most are sucked by cell phones, little productivity in jobs because the concentration is only for cell phones, etc ... and so many other real problems that are univocally associated with cell phone use.
