UK loon woman Tess Christian has not smiled or laughed in over 4 decades in order to avoid wrinkles. Initially, Tess explains, it didn’t start out that way, but instead she picked up the habit in Catholic school due to strict nuns who demanded that the kids “wipe that smile off your face.” However, as she reached adulthood, she concluded that a somber expression looked good on her (highly debatable) and that she assumed it would help her to avoid annoying wrinkles down the road.
