723 Heads Up

I sense that not a few people have been well aware of the fact that smartphones and tablets cause us lots of health problem like text neck, headache, mid-back pain or bad sleep. It's a huge problem but it cannot be helped as long as the technology makes us use them as indispensable tools. Simply put, without losing the benefit and blessing of unlimited access to information over time and place, if we can use it less and less, I'm sure the better our life can be. 

So my friend came up with a remarkable idea to make the world a bit better, that is, to set a certain feature to all the smartphones and tablets (except for emergency) that they never react nor turn on unless we hold them just as high as the position in front of our eyes, (or maybe higher), so that our heads naturally get up and we do not harm our neck and back bones. Isn't it genius?
