No - have not read the book, but thanks for the reminder - I watched part of the PBS "Brain Fitness" series and Tivo'd the rest to enjoy w/my husband.
The series is extremely interesting and quite encouraging.
Sadly, the program was erased before we got a chance to watch it (setting was: keep until next day at 4:00 we did not notice) and had not remembered the name until your post today. Now I know what to search for to watch it again.
The book must be equally enlightening.
I do remember that one of their findings was that the best method for keeping the brain young was: exercise - just walking 20 minutes a day would do (!!!:) and not necessarily all at once.
Thank you for sharing and for always posting such interesting thoughts and findings.
