Re: --What is "YOUR" body made of ?--And How !--
"all the body needs to function is water,
Sugar and oxygen, and a few minerals"
I'm sorry, but this is a gross oversimplication. Protein is required in the form of essential amino acids. There are several essential amino acids that are not manufactured by the body and required from diet.
Also Vitamins are also required - Scurvy is just one example of a disease, caused by having no Vitamin C in the diet. Scurvy killed lots of British sailors before they figured out they needed to carry fruit on the ships.
Supposedly there is a way to live on "Qi" or "Chi" alone, but I've yet to meet anyone like this!!!
In my humble opinion, I'd like to think we are a combination of energy and chemicals. You can't ignore the energic aspect, but the chemical aspect is also very important.
cheers,
