It's not supposed to be a source at all, it's supposed to be a reminder that advice about "staying hydrated" are common—and wrong.

Yes that part I don’t really care about, it’s pretty easy to point to misinformation on the internet. I think the part of your original comment that sticks out to everyone is your idea that generally, over hydration is more of a risk than dehydration.

As an otherwise independent third party, I'd like to gently suggest that you read the words again. Each case, either too much or too little, is given equal weight. I believe confusion may happen there because our brains fill in the blank and in reaching for that language it's typically done so to contrast the subject.

Sorry to intrude with nothing more to contribute.

Fair enough, thanks for the tip. I did write this before I drank a coffee this morning which is probably a questionable way to start the day anyway :D
