Very interesting. Also, you did a great job of explaining why these brain exercises can still have great value in spite of whatever the results were from this particular study. Personally, I look forward to the morning newspaper just to do sudoku and the word jumble. And my husband, who was a patient in the HABIT program, enjoys doing a version of sudoku on his tablet where we can control difficulty level. The pleasure of this little morning ritual gives us plenty of value - whether it improves his brain - or mine - or not! I'm with you - let's stay optimistic about these exercises.
