Yours and my reading styles are very similar. I miss being able to read one thing at a time instead of devouring. I just can’t help myself. I have a tremendous NEED TO KNOW. As I am sure you do too.
I was reading easy books on my own by age four. By seven or eight I was spending hours upon hours reading every encyclopedia volume I could find. Although I am not especially sedentary (I love vigorous exercise and the outdoors) I do spend at least 20 hours a week reading books I am interested in--and my interests are quite varied. Currently I am on a nonfiction binge.
I have developed one reading habit I am not sure many people share: I often start at the end of a book and read toward the beginning (nonfiction, anyway).
