This is the issue with the pneumonia thing for Clinton: while her health is a legitimate question (for both her and Trump), it does not validate crazy conspiracy theories about her well-being. And that can be a hard line for many to toe.It could be Parkinson's....which would explain the forgetfulness if she's having the dementia. No physical tremors I can see....but for some it's mild.
The reality is that, given the absurd number of working hours each day we've seen from Clinton, she cannot be that sick. I cannot speculate on whether she has a viral or bacterial pneumonia, but older people who fare poorly with pneumonia are typically bedridden. Immobility and shallow breathing (from lying in bed) keep the lung partly collapsed, which is a nidus for bacterial infection to form; bedridden patients with viral pneumonia can develop a secondary bacterial pneumonia because of this. But that just isn't the picture we see with Clinton. She's constantly walking, constantly giving interviews, staying constantly active. Pneumonia can have a very benign course. It can also have a very debilitating one, but this just isn't what it looks like.
BTW, I've yet to see anything even remotely indicative of Parkinsons, so let's just lay that one to rest.
