Someone correct me if I'm wrong but, I believe your supposed to divide your weight in half and that is how many ounces of water you should be drinking a day. 1 us gallon=128 us fluid ounces

Aye.. indeed but too much can kill. http://www.sciam.com/article.cfm?id=strange-but-true-drinking-too-much-water-can-kill

Yep, good for skin & digestion.

Not according to this new study Drs. Dan Negoianu and Stanley Goldfarb of the University of Pennsylvania assessed published clinical studies on the benefits of drinking water. They found that while athletes need more water -- along with people who live in hot, dry climates and those with certain diseases -- the average healthy person does not. In fact, the researchers found no evidence to support the common belief that drinking eight glasses of water a day can result in health benefits, which have long been believed to range from improved kidney function to a more luminous skin tone. "It's required for life, and I guess that's led people to think, 'well, if a normal amount is good, then extra might be better,'" Goldfarb told ABC News. "It won't harm you, but you should understand that there's very little, if any, scientific evidence that it's going to benefit you." Some studies did show that an increased water intake does help the kidney remove substances, such as sodium. However, this did not lead to a health benefit. Researchers cound not find conclusive evidence for other theories involving greater water intake, including that it helps fight weight gain by keeping a person feeling full, and it improves skin tone. A study that found that participants who drank more water experienced fewer headaches was found to be too small to be significant. One interesting conclusion was that how fast a person drinks water seems to determine if the body excretes it or retains it. If water is gulped, it will most likely be excreted. If it is sipped slowly, the body will hang on to it. However, the speed of water intake did not indicate any health benefit. The researchers point out that although the studies they reviewed did not prove that there is a clinical benefit of drinking more water, there is also no proof that there isn't one. "Drink when you're thirsty," said Goldfarb. "That's the way your body is designed." The study entitled "Just Add Water" will be published in the June issue of the Journal of the American Society of Nephrology. --------------------------------------------------------------------------------

Obviously it is your bodies drink of choice, and is better for you than, say, any pop or juice product loaded with sugars. However a lot of people already get a good amount of water when you add up the water contained in foods eaten and other drinks consumed daily. If you are thirsty, drink. Thats about all there is to it! You don't need to add unnecessary drinks to your diet just because a study said its good for ya. The only thing drinking a lot of water daily in addition to the food and other drinks you may consume daily is that it will make you need to wee a whole lot more. Some people have even died from drinking too much, as it leeches out vital nutrients in that case!

Only if you have a hangover... really!

Sure. On the other hand, an extreme amount can be fatal (waterlogs the brain) and most drinks can rehydrate almost as much. And you certainly don't need to drink as much as health food programs recommend. No one knows where the rumor you should drink 8 glasses of water a day came from.

if you want your poop to come out soft, you had better drink a lot of water. no water means hard poop. i kid you not.
