There was a news story a week or two ago that explained that swearing makes you feel better. Although, I doubt swearing in print has the same effect...
Wasn't this article about if you received pain and you cussed it made you feel better? like yelling obscenities when you stub your to, or place a toothpick in your toe and kick the wall. (that seriously is wrong, but I remember seeing a contest where someone one tickets to a concert to do this...I was like WOW)
