History & Culture. In April 1917, the United States entered World War I on the side of the Allies. Previously angered by the sinking of Lusitania, President Woodrow Wilson led the nation to war after learning of the Zimmermann Telegram and Germany's resumption of unrestricted submarine warfare.
WATER AND HUMANS. * The human body is more than 60 percent water. Blood is 92 percent water, the brain and muscles are 75 percent water, and bones are about 22 percent water. * A human can survive for a month or more without eating food, but only a week or so without drinking water.
Now lets take a closer look at the importance of water in our own bodies. As babies we are approximately 75 to 80% water and as we grow older this percentage decreases until the percentage is reduced to approximately 60 to 65% for men and 50 to 60% for women. The human brain is about 85% water and our bones are between 10 to 15% water. The chemical structure of water H 2 O and both the hydrogen and oxygen have great importance as life giving properties and a preserving force to our systems. Women have a higher percentage of adipose tissue than men, giving them a lower percentage of water.
