The ability to decode smiles appears to be hardwired into the brain as an aid to survival. Because smiling is essentially a sub-mission signal, ancestral men and women needed to be able to recognise whether an approaching stranger was friendly or aggressive, and those who failed to do this perished.

When you look at the above photograph you'll probably identify actor Hugh Grant. When asked to describe his emotions in this shot, most people describe him as relaxed and happy because of his apparent smiling face. When the shot is turned the right way up, you get a completely different view of the emotional attitude conveyed.

We edited Grant's smile to produce a horrific-looking face but, as you can see; your brain can even identify a smile when a face is upside down. Not only can it do that, but the brain can separate the smile from every other part of the face. This illustrates the powerful effect a smile has on us.
