Well, I see 4 men in there with their arms crossed. I take the arm-crossing as a sign of suppression - against anxiety? I would think that this was extremely stressful to see. One man had has his arms behind his back, which I take as a sign of disassociation. Hillary - her actions speak for themselves. I’d probably do the same thing seeing what she’s probably seeing. Obama - he looks extremely interested in what’s happening, but I don’t think he’s feeling any less stress. To me, he looks like the most stressed person in the room in this photo. And, given all the activity they were watching, I wouldn’t blame him one bit!
