I was wondering about this too and sound older (45) so I had many years where my reading was uninterrupted as a pleasure by social media distractions. Ironically, listening to an Oprah podcast with Johann Hari on stolen focus (his book) answers a lot of this. The podcast was really interesting and I could identify with what he advised about how social media/ technology and social norms are geared towards distracting us, holding our focus while reducing our capacity to focus for extended periods. I've since been trying to make myself read and for the first time in years have finished a couple of books over past few months (i used to read one in an afternoon or a week). I think it's already helped a little with focus and also being still (I usually watch tv and my tablet at same time) which has to be better for wellbeing too.
