The great of water..

Eight is the magic number when it comes to water consumption. For decades, health and nutrition experts have championed drinking 8 ounces of water eight times a day. We get much of the water we need from the foods and beverages (other than water) that we consume. Health experts are downsizing their water recommendations to five or six 8-ounce glasses per day, but if you are physically active you need more at least 7-10 additional ounces for every 15-20 minutes of exercise.
