Smartphone use is not only distracting while driving, but also addictive. They can be destructive to relationships reported a noted university professor.
Cary Cooper, Professor of Organizational Psychology and Health at Lancaster University, warns, "Like television, the light draws you in and numbs your senses. It's the exercise equivalent of treading water and can be both addictive and destructive in the way it occupies your mind without actually stimulating it."
