Input: Consider Input: I thought this book was long, drawn out, and boring. It was too descriptive. To me, the writing style is a lot like Jane Eyre. I don't particularly like that type of book.Plus, it was way too sad and unrealistic. I don't think THAT many bad things could happen to one person.

Output: Negative


Input: Consider Input: If you are not in really good shape this is a great product to get ready for P90X. It does get kind of boring because you are doing the same workouts every other day, but they do work. It is only about 30 mins but it is amazing how well it works.

Output: Positive


Input: Consider Input: Decent product. I had to sleep on it for a few nights and I survived. It is comfortable enough to pass out on It stayed inflated the whole night and deflates well. It comes with a sack for storage, though my folding skills are pretty lame, so fitting it into the bag is a challenge for me.


Output: Positive
