I read the news story just for info and have this to say about it:
1) Newspapers deal in controversy and trauma
2) Water is essential for all living things -- get the book, YOUR BODY'S MANY CRIES FOR WATER and read it cover to cover -- including the section on salt.
3) The instance of an athelete dying due to drinking too much liquid is interesting in that it makes you think she died from drinking water, when in fact, she had ingested a sports drink -- different kind of animal -- water and a sports drink are not identical drinks -- and are only similar because they are liquid. Other than that, they are DIFFERENT. One, water, is necessary for life, the other, a sports drink, contains usually much, much sugar or if not sugar, artifical sweetners, which are chemicals that have some pretty bad side effects. But like I said, news is all about controversy and trauma. At least in this society at this time.
