Take down a musical instrument. Let the beauty we love be what we do. There are hundreds of ways to kneel and kiss the ground. Chlorine, fluoride and a multitude of other toxins from our polluted environment are a major problem, in spite of what the city may tell you.

Bottled water has problems too.
There have been isolated reports of contamination in some water from foreign sources. Some people think that chemicals can leach out of the plastic bottles, but that depends upon how long the water has been sitting in them. It will also get expensive, because you will be drinking a LOT of water on the program that I recommend. The best way to go, is to get a water filter for home use. Before you buy anything, see what your local discount hardware store has in stock.
