Water is more than just a carrier for the biomolecules in life. The greatest change in aging is not in your biomolecules, but in loss of water from your cells. Water’s ultrastructure and its special ability to store information, is the very basis of the living state. Water can be programmed with various frequencies that convey information useful for healing. The “best” water that you can drink to maintain hydration, remove toxins, stay alkaline, keep your cell membranes energized, and maintain the biofield, will be described. New developments in “designer water” will also be discussed.
