I used to use one of those speed reader apps. I found that if I set it at ridiculous speed - 10,000 wpm! - you can still read the words but not really "read" anything i.e. be able to say anything intelligent about what you just "read."

But then I would shift back to 4,000 wpm and suddenly it seemed so easy to keep pace. And the longer you stayed at 10,000 wpm the easier 4,000 became.

I feel our brains are totally up the challenge.
