Context paragraphs:
Computer addiction: Computer addiction can be described as the excessive or compulsive use of the computer which persists despite serious negative consequences for personal, social, or occupational function.  Another clear conceptualization is made by Block, who stated that "Conceptually, the diagnosis is a compulsive-impulsive spectrum disorder that involves online and/or offline computer usage and consists of at least three subtypes: excessive gaming, sexual preoccupations, and e-mail/text messaging".  While it was expected that this new type of addiction would find a place under the compulsive disorders in the DSM-5, the current edition of the "Diagnostic and Statistical Manual of Mental Disorders", it is still counted as an unofficial disorder.  The concept of computer addiction is broadly divided in two types, namely offline computer addiction and online computer addiction.  The term offline computer addiction is normally used when speaking about excessive gaming behavior, which can be practiced both offline and online.  Online computer addiction, also known as Internet addiction, gets more attention in general from scientific research than offline computer addiction, mainly because most cases of computer addiction are related to the excessive use of the Internet.

Life imprisonment: Life imprisonment (also known as imprisonment for life, a life sentence, lifelong incarceration, or life incarceration) is any sentence of imprisonment for a crime under which convicted persons are to remain in prison on unlimited time, traditionally for the rest of their life or until paroled. Crimes for which a person could receive this sentence include murder, attempted murder, conspiracy to commit murder, blasphemy, terrorism, severe child abuse, rape, espionage, treason, high treason, drug dealing, drug trafficking, drug possession, human trafficking, severe cases of fraud, severe cases of financial crimes, aggravated criminal damage in English law, and aggravated cases of arson, kidnapping, burglary, or robbery which result in death or grievous bodily harm, piracy, aircraft hijacking, and in certain cases genocide, ethnic cleansing, crimes against humanity, certain war crimes or any three felonies in case of three strikes law.

Sexual addiction: Sexual addiction, also known as sex addiction, is a state characterized by [[compulsive]] participation or engagement in [[Human sexual activity|sexual activity]], particularly [[sexual intercourse]], despite negative consequences.  Proponents of a [[diagnostic model]] for sexual addiction, as defined here, consider it to be one of several sex-related disorders within an umbrella concept known as [[hypersexual disorder]].  The term "sexual dependence" is also used to refer to people who report being unable to control their [[sexual urges]], behaviors, or thoughts.  Related models of pathological sexual behavior include [[hypersexuality]] (nymphomania and satyriasis), [[erotomania]], [[Don Juanism]] (or Don Juanitaism), and [[paraphilia]]-related disorders.

Internet sex addiction: 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.  It may also be considered a subset of the theorized Internet addiction disorder.  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.

Pornography addiction: Pornography addiction is an addiction model of compulsive sexual activity with concurrent use of pornographic material, despite negative consequences to one's physical, mental, social, or financial well-being.  Universally accepted diagnostic criteria do not exist for pornography addiction or problematic pornography viewing.  The rewarding and reinforcing (i.e., addictive) properties of cybersex have been evidenced using cue reactivity experiments with pornographic cues in humans, which supports the classification of cybersex addiction as a true behavioral addiction.

Exercise addiction: Exercise addiction is a state characterized by a compulsive engagement in any form of physical exercise, despite negative consequences.  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.  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.  Differentiating between addictive and healthy exercise behaviors is difficult but there are key factors in determining which category a person may fall into.  Exercise addiction shows a high comorbidity with eating disorders.

Alcoholic hepatitis: Alcoholic hepatitis is hepatitis (inflammation of the liver) due to excessive intake of alcohol.  It is usually found in association with fatty liver, an early stage of alcoholic liver disease, and may contribute to the progression of fibrosis, leading to cirrhosis.  Signs and symptoms of alcoholic hepatitis include jaundice, ascites (fluid accumulation in the abdominal cavity), fatigue and hepatic encephalopathy (brain dysfunction due to liver failure).  Mild cases are self-limiting, but severe cases have a high risk of death.  Severe cases may be treated with glucocorticoids.

Problem gambling: 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.  Problem gambling is often defined by whether harm is experienced by the gambler or others, rather than by the gambler's behaviour.  Severe problem gambling may be diagnosed as clinical pathological gambling if the gambler meets certain criteria.  Pathological gambling is a common disorder that is associated with both social and family costs.

Alcoholism in family systems: Alcoholism in family systems refers to the conditions in families that enable alcoholism, and the effects of alcoholic behavior by one or more family members on the rest of the family.  Mental health professionals are increasingly considering alcoholism and addiction as diseases that flourish in and are enabled by family systems.  Family members react to the alcoholic with particular behavioral patterns.  They may enable the addiction to continue by shielding the addict from the negative consequences of his actions.  Such behaviors are referred to as codependence.  In this way, the alcoholic is said to suffer from the disease of addiction, whereas the family members suffer from the disease of codependence.

George Wickham: George Wickham is a fictional character created by Jane Austen who appears in her novel "Pride and Prejudice", published in 1813.  George Wickham is introduced as a militia officer who has a shared history with Mr. Darcy.  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.  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.  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.
