I do not pretend to know which effects, such as the habit-forming nature of digital media, or actual physical effects of EMFs, are the greatest cause of the state of constant anxiety now seemingly common to most people, but I don't scoff so easily..... Multi-billion $ industry versus forgotten WHO warning and some buried science re a product to which we are every one addicted. What could go wrong? But then perhaps you give your kids cigarettes in their school lunches?
