Human grooming

Facial expressions

Your face is supposed to
freely convey your emotions

Primal modes of communication

Primates are facial expression champions

How many facial expressions are there?

Scientific research going nowhere

A window on your feelings

Multiple expressions

Stuck with your past on your face

Judging people by their looks

Expressionless, aggressive and smiling faces

The story of the smile

Boomerang facial expressions

How expressive should your face be?
