Something already obvious to anyone who's
ever done a long ride in a cold rain.

A study by Keele University researchers found volunteers
who cursed at will could endure pain nearly 50% longer
than civil-tongued peers.
Dr Stephens, from Keele's school of psychology, came up
with the idea for the study after swearing when he accidentally
hit his thumb with a hammer as he built a garden shed.
He recruited 64 volunteers to take part and each individual
was asked to submerge their hand in a tub of freezing water
for as long as possible while repeating a swear word of their
choice.
They were then asked to repeat the experiment, this time
using a more commonplace word that they would use to
describe a table.
Despite their initial expectations, the researchers found that
the volunteers were able to keep their hands plunged in the
ice water for a longer period of time when repeating the
swear word.
