Water, water everywhere

With the high heat and humidity of the last few days, everyone is either thinking about jumping in the water, or having some cool water to drink.

When you are thirsty, it's because you've lost more than 1 percent of the water in your body. There's lots of interesting facts about water that you may find interesting.

"¢ We all know that our bodies are about 70 percent water, but when a baby is born, its body is 80 percent water.
