Grumpy = More Analytical ?

See this summary of recent research [via boingboing] conducted by the University of New South Wales that includes:

“By contrast, those who experienced a negative mood such as sadness were shown to provide more reliable eyewitnesses accounts and exercise superior thinking and communication skills.”

So to all of y’all who have ever complained about my angst, grumpiness, moodiness or overall negativity sometimes (and you KNOW who you are!): I suppose you’re just jealous of my “superior thinking and communication skills”, huh?
