Share your smile with the world. It's a symbol of friendship and peace.
-Chritie Brinkley
Smile is a sign that a person is happy, joyful, andexcited. Smile is not natural when a person is sad or upset. When we are feeling great, a smile comes naturally. It turns out that by smiling might be the best thing to do when we're ready to shift into a brighter mood.A smile can go a long way. It can start a friendship, dissolve an argument and spread happiness.
Smiling affects certain muscles within the body that make you feel happy. The movement of muscles in your face releases chemicals called endorphins which trigger a positive feeling. These endorphins lower stress levels, which improves your mood. Even if you are not feeling happy, endorphins will trick your body into thinking that you are. So, the more you smile and stimulate your brain to release this chemical, the happier you will feel.
Let us keep in mind that everyday different people we can encounter, and maybe one of those have a big problem and thinks to suicide. Let our smile help them to change there minds. And make a world a better place.
