So water is alive is it?
While this is an interesting idea, that your body is partially not alive, the way it has been presented in this piece is palpable nonsense.
What the good doctor has done is crudely and inaccurately classed organic compounds in the body as "alive" and in-organic as "dead". He has, rather weirdly, included water in the group of things that are "alive". Do you commit murder when you have a drink?
If you took this definition of what is alive and dead then petrol would be very much alive, as would methane gas and good old fashioned ethanol, the intoxicant so many are familiar with.
I love the line "A small part of us is not alive, never has been, and never will be". Actually EVERY small part of us is not alive and never has been. He describes the dead parts in terms of individual atoms or molecules. I know of no definition of life that calls any individual atoms or molecules alive, and that goes for DNA too. A DNA molecule is most emphatically not alive - it cannot do one of the most fundamental of living process, that is replicate itself. It needs to be part of a living cell to do that.
If you were to take any of the elements he has called alive and separated them out they would no more be alive than some of the inorganic "dead" elements he has described. A molecule of protein is no more alive than an atom of iron, or sulphur. It is the combination of all of these components together that make up the organism. And its only the organism as a whole - or any part of it that can live an independent existence such as cells in tissue culture - that can be considered alive.
There are more interesting and much more accurate ways of talking about the "aliveness" and "deadness" of a human body. For example, when you look at someone you only see dead cells, no live ones are visible on the surface of the human body. Every skin cell on the exterior of the body is well and truly dead - like, I hope, this article.
