I purchased the Intex airbed to replace an Aerobed that our cats "loved" too much during a guest visit. Comfort wise, the Intex wins hands down-supportive yet comfortable as well. Convenience wise, it inflates a little slower than our old Aerobed (albeit, there is more to inflate) yet it takes up less room when rolled and stored in the sack that comes with it. The only reason I didn't give it 5 stars is because it is VERY high, so a restless sleeper can fall off pretty easily.

I don't know if you can actually call this music. It is truly terrible. However, I love listening to it for some strange music. ... I am not normally a fan of rap music, but I laugh out loud every time I hear some of these songs. These Cash Money guys should be comedians. Except for Juvenile, since I can't understand anything he says, which is also rather funny. Don't buy it for the music, but it for the comedy.

I regard Dr. Bernstein as the top authority for Diabetes. This book will give a diabetic all the information required to completely understand his/her condition. I do not have the discipline to follow his recommended diet...however, with the understanding of Carbs, I can with diligence control blood sugars. I give more credence to the Glycemic Index than Dr. Bernstein...seems to work for me. I do not hesitate to recommend this book to all diabetics and partners of diabetics!
