[EX Q]: This book was a wellspring of information for me as a newly diagnosed type 2 diabetic. Getting off the cycle of being told to eat complex carbs, seeing my blood glucose spike from doing just what I was told, and getting medications increased again and again, I read what Dr. Bernstein said with interest. After trying his recommendations I can say with no reservations that this book may have saved my life! I highly recommend it to anyone who has pre-diabetes or diabetes and hope that the general medical community opens their eyes. After only one day of this diet my blood glucose readings were close to normal, and continue to stay there, with less medication. My energy levels are high and I have felt better than I have in a long long time. Kudos to you Dr. Bernstein, for daring to say the truth! I recommend both his books and also Dr. Atkins Diabetes Revolution to anyone who wants to learn about diabetes and diet.
[EX A]: Positive

[EX Q]: Beautifully photographed but over-produced historical women's picture on an epic scale. Yes, it has its fans but so do those dime-a-dozen bodice-ripper romance novels on supermarket racks. Still, gorgeous cinematography and a lusher-than-lush musical score can't disguise the fact that this David Lean misfire is an overblown snooze of elephantine proportions. A pallid Sarah Miles manages to suggest what Julie Christie might have done with this part, horribly miscast Robert Mitchum plays a flower-pressing milquetoast and a dazed-looking Christopher Jones is so bad his voice had to be dubbed. However, John Mills received richly-deserved Oscar for his portrayal of village idiot struck dumb by plot inanities he witnesses in mute silence. No wonder he's speechless.
[EX A]: Negative

[EX Q]: I learned a lot about the Eastern Front Luftwaffe. It is as much a study in the personalities as it is a history, strategy book.
