Due to age and the impact of some physical injuries I found myself in a state of not having the energy to do much of anything. I saw Cell Food in a store and bought a bottle. I then researched the product and the vendor claims seemed so scientifically bogus I was going to throw away the bottle I bought. Then I thought -- I paid for it, why not try it. For the first two days it seemed to give me a headache. Then I did started to feel like I was becoming a little more energetic. Not hyper like taking a stimulant - more like improved focus and not feeling worn out. Still being skeptical of the junk science claims I asked my wife to start taking Cell Food and she reported a noticeable physical improvement. I would like to know what is in this stuff and how it really works. Clearly we take O2 into our cells via respiration so I don't buy the increasing O2 via something one drinks claim. Cell Food has a definite taste so there is something in it. It is not just water. I do plan to keep taking it.

As with all the great Dummies books, this one follows suit. It is thorough and covers all that you need to navigate Quickbooks 2012 as a newbie or an Advanced user needing an update. Highly suggest it.
