Do you remember how cellular phones look like when they were first introduced into the market? They were so huge and grotesque-looking that some of us might not be able to imagine how they looked like considering how sleek and handy our current models are and not to mention how sophisticated they have become.
There was also a lot of hype about the health hazards of using cellular phones for extended periods of time. With the advancement of technology, phone mechanisms have improved a great deal which have lessened the negative effects. Of course, one has to take certain precautions to try to avoid or at least minimise the health hazards.
