Very good article here that brings up a few points. A lot of is by a sports psychologist from the university of Salford so I would give it more credence than some of the psychobabble that is being spouted. It seems that while biting is rare in adults it is more common in sport than in 'real life'. It would appear that it is often the result of frustration and close proximity with your 'opponent'. I would also point out that a 10 match ban is not the harshest penalty for biting either. Back in 1994 South African Johan le Roux received an 18 month ban for biting the ear of an opponent. Of course that was rugby where players are not likely to go stage theatrical dives at the drop of a hat...
