I found this an interesting blog post. I'd listened to his book Super Crunchers!, and he teaches what is probably the best law school currently in the U.S. Anyway, I do wonder about the electronic phenomena and how it may affect our ability to concentrate and focus. I know, I know, here I am making a short blog post, and I certainly read them. But still, we do have to be careful. Remember: you crap-detector must be on 24-7. Anyway, this post and the couple of others that he cites to are very thought provoking.
Check out this related post, and this one.
