Drink 8 glasses of water every day.Water is essential for all healthy body functions. Centenarians from around the globe cite their native water as the source of their health and longevity - and the scientists agree with them. What they all have in common is pure water sources located far from any city, free from chemicals and toxins.
Choose filtered water; the best filtration processes are the ones that use activated charcoal, which removes the impurities but leaves the water-soluble minerals. Also, do not store water in plastic containers because the polychlorinated biphenyls (PCBs) can leach into the water.
