An interesting discussion, an avidreader for many years I now find that much of my pleasure from reading is diminished from reduced eyesight, concentration and memory and I just cant get the same feeling out of listening so read slower and less frequently. I have always read two kinds of books in two different ways, a novel, particularly ones I enjoy, I will sit down and simply inhale, reading the content rather than the individual words. A technical book I use much the same method to get to the bit of information I need and then read each word and the meanings of the content with much more care, I have no idea how I came to do this automatically but over the years it has worked for me.
I now rarely pick up a novel and do not get as much pleasure from it as I used to when I do, I do have a number of my favorites on my bookshelf and do / have reread most of them several times however I find its best if they are left 'on the shelf' for years rather than months.
PS I worry about our youth who are totally lost if they dont have their whole world right at their finger tips …. much of which is fiction presented as fact!
