I am just beginning to read about carbon. Let me just quick ask you if you are very lean. There is a whole long chapter with a million facts about carbon in Jensen's The Chemistry of Man. You probably already know that the word carbohydrates comes from carbon. And the lungs' job is to get rid of the waste from the usage of carbohydrates. (CO2) Some people's bodies have a hard time making use of carbon, mostly due to lack of other minerals such as potassium and sodium carbonate. If someone has a hard time using carbohydrates, they may end up with diabetes. (I don't know if this will lead to anything or not, but it is interesting.) The only thing I can think of right now is that if we have a problem utilizing carbon, and breathing into a bag takes away lightheadedness, maybe rebreathing the CO2 is a way of obtaining carbon? I put the question mark at the end because I in no way want it to sound like a fact.
The other thing that I will have to look up online is if there is a connection between any parasite and carbon. What do you think. The book says that carbon can be as hard as a diamond. Edit in: Just looked it up. How does this sound? Carbon nanofibers.
