Pure water is essential for all life
Consider this:
- The average human body is comprised of 60% water
- Your brain is 70% water
- Your blood is 83% water
- Your muscles are 75% water
- Your bones are 22% water
- Your lungs are almost 90% water
Humans can live for a month or more with out food, but will only survive about a week with out water. When water is so important, you need to be sure to be drinking pure water.
