This is an excellent point. I got rid of my smartphone a little bit ago and went back to a flip phone. I find that now, when I go to restaurants, I inhale books on my kindle because it's one of those situations where I'm not getting constant notification dings that need my attention. I'm starting to think this is less of a "my attention span is worse" thing and more of a "I read so many books when I was in school because I got bored, had no internet at home but had books"
