One blogger recently posted how he being a positive smiling person attracts negative comments, like he must be crazy. I had been thinking about that, more so about TV faces. I channel surf w/ sound off till I find a person smiling..boy some days it's just cooking shows where people smile.
Then I read this so I'm sharing it.

(PhysOrg.com) -- In any social situation, we need to be aware of
threats to our own safety from other people. That may be why our brains
are better attuned to remembering the identity of angry faces over
short periods of time.
As well as discovering improved
short term memory for angry faces, researchers at Bangor University's
School of Psychology have located a key brain area that responds more
actively to angry than happy or neutral faces. This discovery is being
published in a scientific paper today by PLoS ONE
"The fact that we have located the process taking place deep in the
brain- in an area associated with primitive emotional response systems-
suggests that the ability to retain angry faces in our short term
memory is associated with our survival instincts," explains Dr Margaret
Jackson, the paper's lead author.
She describes this finding as part of a 'threat superiority
effect'. It implies that the signal from the newly identified area of
activity boosts the brain processing for face identification- as a
priority activity relevant to our safety.

"The ability to remember who is angry may have been of evolutionary
importance in enabling us to respond to a threat situation. Remembering
who's happy is less important as it bears no relation to our own
immediate safety," explains Jackson.
