I

We've all heard that, but what does it mean?  How big is each glass?  Does juice count? How about coffee? Beer? Does it matter how big I am? Can I get them all out of the way before 9 AM?

I'm in the water business and I wasn't sure how to answer any of these questions, except for the beer one.  So I looked into it and I found a recently published (Short) article out of Sydney, Australia that nails it.  Enjoy!  Don't Do it!
