Reading a book is not really passive. Especially if it's a good book. You have to constantly imagine the layouts and the connections the book is trying to draw. For me, after years of Internet, getting back to books made me appreciate my younger self because books need active imagination and follow-through in the brain. I was able to do that effortlessly when I was a child. In fact, if you read all the HN comments the way you read books, it will be challenging(if you have no book reading habits).
