Nearly 2.4 billion people around the world used a smartphone in 2017. By the end of 2018, more than a third of the global population will be using a smartphone. Those numbers -- from Mobile Marketing Magazine -- sound great, don’t they? More people will have more information at their fingertips. However, smartphone technology can be a double-edged sword. On the one hand, it sends us unlimited amounts of information. We don’t have to wait. Our devices ring, ping, vibrate and light up with the latest news from family, friends and around the world. On the other hand, this immediate access to information may become an addiction. And it may make some people feel lonely, anxious and depressed.
