In fact, over five-sixths of the weight and bulk of our bodies is made up of water.
Some one has quaintly, but truthfully, described the human body as composed of a few pounds of charcoal, a bushel of air, half a peck of lime, and a couple of handfuls of salt dissolved in four buckets of water.

The reason why nearly all our foods, as we have seen, contain such large amounts of water is that they, also, are the results of life--the tissues and products of plants or animals.
Water Frees the Body from Waste Substances.

Water in the body, then, is necessary to life itself.

But another most important use is to wash out all the waste substances from the different organs and tissues and carry them to the liver, the kidneys, the lungs, and the skin, where they can be burned up and got rid of.

We must keep our bodies well flushed with water, just as we should keep a free current of water flowing through our drain-pipes and sewers.
It Keeps the Body from Getting Over-heated.
