When somebody is studying the phenomenon of viruses ,he can see that when viruses are not coming in contact with a host organism, they are a sum of chemical compounds that not fulfill the criteria to be considered as life.While on the other hand they start reacting with a host, or in other words they start making chemical reactions with the compounds of the host,they become alive.The same thing happen with prions ,which are proteinaceous compounds that while they react with proteins of the host, they become alive in a way.
Lets hypothesize that we make the hypothesis that:No living organism is possible to remain unchanged structurally.Lets hypothesize that this rule is principal in nature and nothing could go beyond it or prove that it is untrue.
What would that mean to the way that we see the world?
First of all lets make clear what we mean: An organism that would remain unchanged structurally dyring a very small period of time,would be considered as not living for that period. When we say unchanged we mean of course that there are not taking place chemical reaction inside it.Maybe there is a single cell inside an organism that is unchanged,but the rest of the cells are changing. We say then that this organism has a dead cell.,but the organism as a whole is alive.Maybe this cell would be able to regain life if it react with the appropriate signals. But maybe not.
If we want to see the consequences of our hypothesis in the nature we meet the question:what is the least that can be considered as life?For example, a mitochondrion can be considered life according to what we said, but a simple chemical molecule cannot,unless it reacts with another molecule or substance.At the moment of the reaction these two substances are the least that is considerd life.So, a simple chemical reaction as long as it happens ,is the simpliest form of life, or else, the sparkle of life.That means that the superior organisms as well as all the organism is a summation of chemical reactions.
The advantages of the hypethesis that we made is that we can explain successfully the prions and the viruses.
Another important consequence of the hypothesis is this:Living creatures are the sum of their chemical reactions as we said.While they are getting older,they are suffering a process that is called aging.They are changing especially structurally.Obviously they are getting different.That means that the chemical reactions that are composing their body,are different from that that were before.If the chemical reaction were remaining unchanged forever,then the body would be the same,and that means that the body would stay forever young and forever alive.
Lets see now a simple chemical reaction A+B”}C+D.Lets consider that C and D are gases and are expelled from the place of the reaction.The quantity of A and B will get lesser and lesser because they are becoming C and D,Or else they are suffering a chemical transformation.
Lets see now another chemical reaction:A+B---}C+D--}E+F
Lets consider that E and F are gasses.That means that the quantities of A,B,C,D will be lowering unless we put in the mixture exactly the quantities of A and B that is being transformed into C and D every moment.So there is an exact amount, as well as exact rhythm of adding A and B that would keep the reaction unchangeable.Lets consider now a very simple organism that is composed from the reactions :A+B--}C+D--}E+F . . . . --}Y+Z.Lets say that A and B are food supplements and Y and Z are compounds expelled from the organism.Of course the real organisms are much more complicated.If that organism eat theoretically a certain amount of food in acertain way, then the reactions of this organism would remained the same forever.[C,D,E,F . . are all compounds of the organism.].If we didn't give the exact food ,then the reaction would change ,dependently on the how far we are from that ideal food .In the same manner we can say that all living organisms are a sum of chemical reactions that start with digestion,and end with the waste products of metabolism.
As a result we can say that in a theoretical basis,if an orgasism eated exactly a certain amount,quality and quantity of foods in acertain way,then it could prevent the changing of its reactions and as a result it could prevent the aging process,expanding its lifespan.Of course this is something very difficult to happen in real life because there are numerous things that plays their role and of course things are not that simple.
One important clue that suggests that what we said is true, is the recent discovery that living organisms that follow a calorie restricted diet,can expand their lifetime, in some cases as long as 60 per cent.This is not a proof that what we said is true,but it is positive to find that the changing of caloric menu has as a result a change in the lifespan.Perhaps a certain diet causes an ever greater expansion.It remains to be proved . . . . ..
The new hypothesis also says that life existed before the first cell,in the form of chemical reactions . to be continued

Hi Minaras,
I see no one has yet responded to your topic proposal. Let me know if you're still around and I'll take a look at it.
