Interesting Fact - Facial Expressions

 According to research carried out at Ohio State University, the average human only makes 21 facial expressions.

(There are six core emotions: happiness, sadness, fear, anger, surprise and disgust, but human Faces Can express21 distinct emotions, combining emotions, such as happily surprised or sadly angry. 

However, according to research carried out at the University of Glasgow human faces might only be able to make four universally recognized facial expressions. They argue that shared key facial signals should be combined:

the wrinkled nose: fear and disgust

widened eyes: fear and surprise

I'm sure my face has shown more than 21 expressions just in the time it took me to write this. Perhaps they didn't count the tongue sticking out of the side of the mouth to help concentration as an expression.)
