A serious condition which has roughly a dozen sufferers world-wide. Sufferers of TPS (Tarsonic Polarity Syndrome) appear to have a buttocks (arse, bum, ass, etc) for a face. The condition only affects the exterior of the body so beneath the skin are eyes, mouth and nasel passages.
Also, if you are a sufferer of TPS, please avoid eating chilli due to side effects.
