I’m not a doctor.
But I do have a little common sense. And I observe things.
One of the things that I have noticed over the years is I’ve never known anyone, and I know and have seen a lot of people over the years, “pass out” from dehydration.
It’s pretty damn simple, especially for someone with a not exactly strenuous lifestyle to stay hydrated.
I have known people to become dehydrated. Back in the day, during August football practices it was standard practice to administer salt pills. And terminally ill people.
The good doctor might want to ask me “How do you keep the most powerful woman in the world, possibly the next president, hydrated?”
Note also that all of these people have handlers, and if they are at a podium, water is always provided. Hillary more than most (because of the coughing) frequently sips water while speaking at events.
She drinks, and she drinks, and she drinks, and her people ask “Can I get you more water?”
And then she keels over and people say, “I guess she was dehydrated.”
I don’t think so.
