For those who have been know to swear a time or two:
"Scientists at England's Keele University say people swear when they hurt themselves because it actually reduces the pain.
The lead researcher got the idea after listening to his wife swear uncontrollably while delivering their child.
The study had men and women place a hand in a bucket of ice water for as long as they could stomach the pain.
Scientists found that the participants could tolerate the pain for longer periods of time when bellowing out curse words."
Unfortunately this story came out 2 days too late. Had I known it was "anesthetic", I would have let off a string of curses that would make a sailor blush while having my arm twisted and pulled to get the X-rays done. Instead I just held my breath through it and then said "thank you so much" to the X-ray tech-sadist after.
But now I know for the future.
