It's a well-known 'fact' that it's impossible to lick your own elbow - go ahead, try it- but whilst most of us will never manage it, for Adrianne Lewis it's easy.That's because Adrianne has what is possibly the world's longest tongue. At 4 inches long she can use it to lick her nose, her elbow and even her own eye. She's even applied to the Guinness Book Of Records for an assessment to see if she could steal the crown from current longest tongue record-holder Nick Stoeberl whose tongue was measured at 3.97 inches back in 2012. Adrianne is often asked whether she has a particularly strong sense of taste thanks to her extraordinarily long tongue - but she says it doesn't work like that. According to her, she's a picky eater but has a particular penchant for mustard - which she carries around everywhere with her in her handbag.
