<P0-S0> George Wickham is a fictional character created by Jane Austen who appears in her novel "Pride and Prejudice", published in 1813. <P0-S1>  George Wickham is introduced as a militia officer who has a shared history with Mr. Darcy. <P0-S2>  Wickham's charming demeanour and his story of being badly treated by Darcy attracts the sympathy of the heroine, Elizabeth Bennet, to the point that she is warned by her aunt not to fall in love and marry him. <P0-S3>  It is revealed through the course of the story that George Wickham's true nature is that of a manipulative unprincipled layabout, a ne'er-do-well wastrel, compulsive liar (talking out of both sides of mouth, and using the truth to make his falsehoods very believable) and a degenerate, compulsive gambler, a seducer and a libertine, living the lifestyle of a rake. <P0-S4>  Lacking the finances to pay for his lifestyle, he gambles regularly (not just because he is a degenerate compulsive gambler and has no sense of economy) and cons credit from tradesman and shopkeepers and skips out on paying-up. <SEP> <P1-S0> Internet sex addiction, also known as cybersex addiction, has been proposed as a sexual addiction characterized by virtual Internet sexual activity that causes serious negative consequences to one's physical, mental, social, and/or financial well-being. <P1-S1>  It may also be considered a subset of the theorized Internet addiction disorder. <P1-S2>  Internet sex addiction manifests various behaviours: reading erotic stories; viewing, downloading or trading online pornography; online activity in adult fantasy chat rooms; cybersex relationships; masturbation while engaged in online activity that contributes to one's sexual arousal; the search for offline sexual partners and information about sexual activity. <SEP> <P2-S0> Problem gambling (or ludomania, but usually referred to as "gambling addiction" or "compulsive gambling") is an urge to gamble continuously despite harmful negative consequences or a desire to stop. <P2-S1>  Problem gambling is often defined by whether harm is experienced by the gambler or others, rather than by the gambler's behaviour. <P2-S2>  Severe problem gambling may be diagnosed as clinical pathological gambling if the gambler meets certain criteria. <P2-S3>  Pathological gambling is a common disorder that is associated with both social and family costs. <SEP> <P3-S0> Exercise addiction is a state characterized by a compulsive engagement in any form of physical exercise, despite negative consequences. <P3-S1>  While regular exercise is generally a healthy activity, exercise addiction generally involves performing excessive amounts of exercise to the detriment of physical health, spending too much time exercising to the detriment of personal and professional life, and exercising regardless of physical injury. <P3-S2>  It may also involve a state of dependence upon regular exercise which involves the occurrence of severe withdrawal symptoms when the individual is unable to exercise. <P3-S3>  Differentiating between addictive and healthy exercise behaviors is difficult but there are key factors in determining which category a person may fall into. <P3-S4>  Exercise addiction shows a high comorbidity with eating disorders.
