Here’s the thing.
If your arms are held behind your back it is substantially easier for other people to support you since your arms won’t rise up and will allow someone the leverage/grasp needed to provide support.
This is not a natural position.
Whether it’s from fainting or some neurological disorder is irrelevant.
What is relevant is if this “Condition”, is NEW?
Now. As I said before. I have seen other images/videos of Hillary holding her arms behind her back while needing help. Therefore, it is not likely to be a NEW condition, but something that virtually all of her “Handlers” and probably her media know about.
There is a massive media cover-up of Hillary’s health.
I have the same suspicion you do, or at least think it’s valid. My only nitpicky point was that it probably would not be taught as a “fainting” aid, but might well be taught as a “seizure” aid. And totally agree, whatever is going on with respect to her seizures is not new. I also agree that the press is in on the secret.
