I think that smiling can indeed change the mood, of yourself and everyone around. As a kid and teen I didn't smile too much, but then I decided to change that and learn to smile more. As a result, most of my smiling is fake (forced), but it is apparently convincing enough. I do move muscles around my eyes. Strangely, this fake smiling improves my mood too, so I sometimes smile this way to myself! The most difficult thing to fake is the lingering of the smile at its end, and making it disappear gradually.

Really?! I can voluntarily control all muscles of my face (at least those that participate in facial expressions). I am shocked to learn that other people can't!
