Query: Scientifically factual. Not at all a huge pile of crap.

This book, which is filled to the brim with scientific facts and theory, helped me a great deal. I can now hang out and stare in the Victoria's Secret dressing rooms without leaving my stuffy, grime-encrusted apartment. I can also see through Bill Gates' eyes and have stolen all the code to Longhorn and sold it to Steve Jobs for $600. So this fine scientific tome made me a profit! Money well spent. Thanks, Mr. Rifat!P.S....I would have rated this book 5 stars, but the fact that it's utter b.s. that only an acid casualty would believe drops it a full star.
