[EX Q]: If you enjoy the hype of the Academy Awards, this is the book for you. Plenty of behind-the-scenes action that you're not going to find by simply watching the Academy Awards. It's gossipy, dishy, and dirty...a definite guilty pleasure. Great index of past Academy Award winners and nominees as well.
[EX A]: Positive

[EX Q]: Currently, there are no wholes throughout the bed. But, for some reason when I wake up. The bed is already out of air. I only weigh 120lbs. I don't understand why it does that. Please save your money, when you start to have the same problem.
[EX A]: Negative

[EX Q]: These CO detectors are mandatory in many states now. I happen that the man who cleans my carpets is the Captain of the town fire dept (also up for promotion to chief), and he always points out my fire hazards or things I do or don't really need to do. I had my first CO detector up on the ceiling next to my smoke detector. He told me it di not need to be on the ceiling, and it's easier to get a plug in one so you don't have to worry about the battery aspect. Then incidentally my ceiling one broke somehow. So I bought this one, plugged it in, in the hallway near my bedroom......he said to do that so you can hear it quickly, and loudly. It's doing it's thing. A little pricey, but actually one of the cheaper ones. He approved!
