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 Output:
Negative

Ex Input:
I used to think that there was no strategy, per se, to fishing a lake--a big tub of water you trolled until you got an arbitrary hit.This book takes an almost forensic view of a lake's features--water layers, vegetation, etc.--and shows how to read them and catch fish. It's much more detailed than I expected and I came away with a real sense of how to find trout as quickly as possible.

Ex Output:

Positive
