Or, perhaps, “empathy enhancing.”
I take from the above video that maybe “hot heads” should not just count to ten in an effort to not blow up at other people, but perhaps try yawning (“cool braining” or “empathy enhancing”) as well.
Since yawning sets up an empathic trigger in the brain, maybe nonviolent protest organizers should ask event gatherers to engage in collective yawning (so as to enhance their subsequent love and peace vibe). A potential slogan: “Activists that yawn together, orgy together!”
Or something like that. All you need is yawn.
