Probably not intended, but still :-)
Smartphones can be a hazard when in the wrong hands; this fact has been established by distracted users spanning the globe. Some people, caught up in the task at hand, wander into traffic, into closed doors, trip on curbs, and other sorts of humiliating things. While being absorbed in messaging is often the cause, the compulsion to take a selfie during any moment that is possibly noteworthy has led to some unfortunate situations of its own.
Take, for instance, the man in the video below. We don’t know who he is. We don’t know where he is from. What we do know is that one moment he was walking down a pier, and the next he was seemingly planning to take a selfie of a live TV interview nearby.
