10/26/15: How Friendships Matter for Happiness
So we've talked about marriage and children [links]. Now, let's talk about friends. There's a video!
This is not that video, but I'm leaving it here anyway:
The actual video points out that we're wired to make friends when we're in new situations (doesn't mean we're necessarily that good at it, but I'm not good at a lot of these things, am I?). But even our non-human primate relatives find value in "non-kin alliances", which are shown to increase oxtocin and decrease cortisol. When we have friends, we know we have support, so we don't stress out as much.
