A person's ability to recognize and "share" others' emotions can be inhibited when they can't mimic faces, even from something as simple as long-term pacifier use.

When you're smiling, the whole world smiles with you

Contagious smiling (and frowning and scowling and so on) is the basis of reading others' emotions and registering how you should, in turn, feel.

We tend to mimic the smiles or frowns of others because it helps us better understand what other people are feeling, allowing us to respond appropriately.

Evidence shows that an instinct for facial mimicry allows us to empathize with and even experience other people's feelings.

“Facial mimicry certainly plays some role, and perhaps a key role, in understanding other people’s emotional states,” Dr. Kevin Ochsner

We are unconsciously learning things by what we see and that's why infants mimic their parents behavior. When they smile to them, they smile back.

Each time you smile, you throw a little feel-good party in your brain. The act of smiling activates neural messaging that benefits your health and happiness.

smiling activates the release of neuropeptides that work toward fighting off stress.

the serotonin release brought on by your smile serves as an anti-depressant/mood lifter.

when you view a person smiling, you actually feel rewarded.

When you smile,you are creating a symbiotic relationship that allows both of you to release feel-good chemicals in your brain, activate reward centers, make you both more attractive, and increase the chances of you both living longer, healthier lives.

First stage: You see an expressive face You need to know what the expression means so you can react effectively.

Second stage: You simulate the facial expression Simulation uses the same areas of your brain that cause your facial expressions- it may therefore cause you to mimic the expression.

Third stage: The simulation tells you how it feels to make that expression The context or your knowledge about the expresser may have an influence.

This quick, automatic, and unconscious process allows you to connect the subtle emotion signals of others to your own emotion experiences.

Smiling makes us happier Smiling triggers a reduction in stress-enhancing hormones and increases the production of mood-enhancing hormones.

Even forcing a “fake” smile when you’re not truly feeling it has been shown to reduce stress and result in more positive feelings.

Genuine smiles might help people see eye-to-eye during interactions. People who often make genuine smiles may have an easier time convincing others to adopt their goals.

I think on 'ER,' my other long-running show, I had some ideas about what's going on. 'Stargate Universe,' they were kind of secretive too a little bit about what they wanted to do, but I kind of liked working this way. I like the surprises, and I like knowing just enough to work on the character.

As far as same-sex marriage, I really would want to think about that a lot more given the fact that my focus would be always on the child. The innocent should not be given more even burdens than what is absolutely necessary.

By the time I was 15 and I stepped in the high school gym, I was just stronger than everybody.

Actors spend most of their time out of work, so I actually spend more time making furniture. The thing about furniture that's much better than acting is that it's just me. There's no director, no script - the concept is me, unless a client wants something.

When I produce a movie - and I've produced a number of movies, unlike Arnold - yes, I'm frustrated when the union says you can't do this, you can't work past that hour, you've got to break for lunch. But ultimately, they're right. What they do is for everyone's benefit.

To help staff recharge and think better, companies are setting aside quiet places to relax, practise yoga or even take a nap. With hi-tech giants such as Hewlett-Packard and Microsoft underlining the pitfalls of being 'always on,' firms are imposing speed limits on the information superhighway.

What my character is or how many jails I have lounged in, or wards or walls or wassails, how many lonely-heart poetry readings I have dodged, is beside the point. A man's soul or lack of it will be evident with what he can carve upon a white sheet of paper.

Life is too short to miss out on the beautiful things like a double cheeseburger.

Last night I dreamed of a small consolation enjoyed only by the blind: Nobody knows the trouble I've not seen!

On a book like 'X-Men,' you have to stay true to the established fiction, working with editors to ensure continuity, sometimes across multiple titles.

Well, I was 29 years old when I came to the United States Senate, and I have learned a lot.

There are no heroes in most of my stories. I look at our society with a critical eye and find nothing extraordinary in the people I see.
