1. When you smile at others you send the message that you are at ease with yourself and at ease with other people.

2. In a work situation, a smile says you’re flexible, competent, intelligent and able to cope with challenges.

3. People who smile are also believed to be honest, trustworthy and reliable.

4. A large smile says that you are an open and accepting individual.

5. A genuine smile is one where the skin around your eyes bunches up. This is one of the best ways of winning friends (as it says that you are warm, non-judgmental and approachable.)

6.  However, a fake smile (where you smile with your mouth but not your eyes) is a sign that you are suppressing your emotions. A fake smile is usually regarded with suspicion, and causes people to back off and conceal their true self from you.
