Pneumonia.....Heat stroke.... alleged coughing from allergies. It's hard to have heat stroke when it's 75 degrees. Here's my theory: it's 9/11 and Hillary is celebrating by drinking heavily ( maybe booze, maybe cough syrup) and she always dresses like it's zero degrees. So the alcohol ( either from booze, from cough syrup or a combination) dehydrates her, she has way too many warm clothes on and she is perspiring because she is (choose one) nervous, under stress or anxious. With the warm clothes, there is no ventilation, she becomes hot, her concussion symptoms kick in, becomes faint and her metal leg braces ( why do you think she always wears pant suits) will no longer support her weight. ( btw, leg braces would make it difficult to traverse stairs, requiring assistance). It takes 3 people to get her in the van. In a few hours, several cups of coffee and probably a shower ( because you know she reeked of body odor), she was able to be seen long enough to say she was ok.
So....other than leg braces, fainting spells, pneumonia, concussion, memory loss, maybe parkinsons, possible stroke, allergies, blood clots in the brain, she is as healthy as a horse.
