So we look at the Vagus nerve, which is tied to social connection. It's actually pretty interesting; it ties to communication, to mood, to our immune systems, to our posture... I mean, you could argue that the brain or spine do the same thing, but still, it's pretty interesting, and I would explain it so badly, so go look at the Wikipedia page.
Next, we look at oxytocin (which my spellcheck insists should read Oxycontin. Thanks, Chrome). Oxytocin makes us more generous, more trusting, more empathetic, and less stressed out.
Good stuff. Next up is another article, so that'll wait til another day.
