I didn't really know what speed reading is. After some explanations in this thread, it would have no point in my reading life now. I might have liked it way back in school for some stuff, but I only read fiction now. And I read every word, I don't skim. I just read fast, naturally.
But really, with my puny human life span, it wouldn't matter if I could read 4 books a day, I still wouldn't live long enough to read all the books I want to read or have in various tbr piles. Especially since I keep adding to those piles.
Now that the Olympics and US Open are over, I might be able to get back to my normal reading. Still watching the paralympics though. In a good month, I can read a book a day. But mostly average one every 2 days. No speed reading involved, just total absorption reading. Which means if the book is good, I can get into it and be gone for a while.
I am probably about twice as fast reading on my kindles than I was on paperback the last view years before Kindle. That is because my eyes got worse and I needed the even flat text and larger font and e-ink is just such a joy to my eyes. So less eye strain and faster reading. And not having to pry open a tight paperback and holding it helps too. No text curving into the spine and no squinting.
