A number of years ago I heard my wife explain the importance of pH to one of our children who was doing a report in Biology. She explained it in such a simple way that even I got it. She said "remember when we had the fish tank? and we checked the water pH daily. What happend that one week that no one checked the water? " " the fish died" the child said. "exactly. For that same reason we check the pool water too. Now, if the human body is made of 86% water, what will happen to us if our pH is not balanced?" " We'll probably get sick and die, like the fish" our child said. That's the importance of pH, It's the differance between health and illness....life and death.
