This is a book I'm selling after I've finished reading it. I handled it with care as much as possible. There's a slight crease on the edge of the book. I am a non-smoker, so there are no unpleasant odors. This book explains philosophical approaches while focusing on our psychology of constantly checking our smartphones. I think it's a book where you'll often be made aware of things you do unconsciously.
