I think the "Air Pressure" in the title is meant, in a way, literally. Speaking for myself, I experience extreme anxiety-right now I feel stifled, like I can't breath, and there's a painful headache that comes with it.
I couldn't read the text in the intro fast enough =(, a pause button would be nice, LOVE the series btw, but if anyone has a youtube link where I can watch it, it would be much appreciated.
