"She doesn't blink..."
First time I saw the documentary I didn't really notice because the scam/fraud/conspiracy was too captivating. But during the second viewing I realized that it's true what the one female employee said: Elizabeth Holmes very scarcely blinks! That's so unnatural.
Normal people blink 15 to 20 times a minute (otherwise your eyes dry out and become irritated). So this means that she must have consciously trained herself not to blink. What a bizarre thing to do. Why would anyone do that? Does she think that not blinking projects confidence? Or maybe she wants to be intimidating? Didn't Steve Jobs blink?
