Can my Smart Phone hurt me?

A lot of people believe that a smartphone is dangerous. There have been endless discussions about cell phones and cancer, for example. In reviewing the data, there is none to show that microwaves such as those used in cell phones cause brain tumors. On TV about 10 years ago, a cell phone was shone to cook popcorn on a table. What was not shown was the radiant heater underneath the table. This was hardly convincing and made cell phones as a cause of brain tumors highly unlikely.
