Interesting Fact - Pain

According to research carried out at the National University of Singapore, screaming "ow", or "ouch" can ease pain.
(In the research they found that being vocal about your suffering helps you to tolerate pain longer.

The problem with that is I don't want to tolerate pain, I don't want to be in pain. I wonder what "Aagh!" does.)

Chinese - 'Aiyao!' 
French - 'Aïe!'
