Water is essential for life

Water is a fundamental part of our lives. It is easy to forget how completely we depend on it. Human survival is dependent on water - water has been ranked by experts as second only to oxygen as essential for life. The average adult body is 55 to 75% water. 2/3 of your body weight is water (40 to 50 quarts). A human embryo is more than 80% water. A newborn baby is 74% water. Everyday your body must replace 2 1/2 quarts of water.
