Does smiling make one happy?

“Smile, it’ll put you in a good mood! “Wise advice? Oh yes, discovered an international team of researchers. A smile does make you feel good, even if it’s forced! The 120 study participants had to hold a pencil between their teeth to activate the facial muscles that contract when you smile. They then had to evaluate the expression of people whose image was presented to them. Their perception of expressions was more favourable when they had the pen in their mouth, forcing them to smile. Activating these muscles would stimulate the amygdala, the emotional center of the brain, to produce neurotransmitters that lead to a state of emotional well-being.
