Water - Drink you are thirsty or not...Drink it.....

Water the source of Life..............
"This one is almost too easy. Drinking five glasses of water a day can reduce your chances of getting a heart attack by 50%. Other fluids like juice, tea, or milk won't do it, your body needs water. Remember, water keeps your body hydrated, which allows your kidneys to function properly, your stomach to digest, it keeps your joints lubricated, your lungs breathing, your temperature warm, and your body to feel energized and alive. If your feeling lethargic or have a headache, its a good possibility that you're just dehydrated. It's your body reminding you to go get a glass of water."
