Water water everywhere...

...how many drops to drink?

There's a common bit of wisdom floating around out there that we're supposed to drink about 8 cups of water per day. I've been skeptical about this wisdom ever since I tried to get those 8 cups one time and was required to leave my desk about 16 times. The 8 cups rule is often accompanied by a number of other dubious claims about water, such as that 75% of Americans are chronically dehydrated, or that water cures certain diseases and ailments .

It turns out that it's "wisdom" and not wisdom. The 8 cups rule is an exaggeration, and we get most of the water that we need from the food we eat. The rest of the claims have no scientific basis.

Snopes contains a great deal of information on other urban myths, and I'm not going to post on all of them. In my experience, however, the 8 cup rule and accompanying "wisdom" is rather pervasive. It even appears on the bulletin boards in the hallowed halls of academia, where at least some of us should know better.

How do you know that Snopes has the official truth about water? Maybe they're the ones who are trying to deceive you. Maybe they own a supermarket chain.
