Context: Death from laughter is a rare form of death, usually resulting from cardiac arrest or asphyxiation, caused by a fit of laughter. Instances of death by laughter have been recorded from the times of ancient Greece to the modern day.
 Question: can you have a heart attack from laughing Context: Crayfish, also known as crawfish, crawdads, crawldads, freshwater lobsters, mountain lobsters, mudbugs or yabbies, are freshwater crustaceans resembling small lobsters (to which they are related). Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams where there is running fresh water, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species such as Procambarus clarkii are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus.
 Question: is there a difference between crayfish and crawfish Context: A tornado watch (SAME code: TOA) is issued when weather conditions are favorable for the development of severe thunderstorms called a supercell that are capable of producing tornadoes. A tornado watch therefore implies that it is also a severe thunderstorm watch. A tornado watch must not be confused with a tornado warning. In most cases, the potential exists for large hail and/or damaging winds in addition to tornadoes.
 Question: does a tornado watch mean there is a tornado Context: The delivery of a no-ball results in one run -- two under some regulations -- to be added to the batting team's score, and an additional ball must be bowled. In addition, the number of ways in which the batsman can be given out is reduced to three. In shorter competition cricket, a batsman receives a 'free hit' on the ball after any kind of no-ball (see below). This means the batsman can freely hit one ball with no danger of being out in most ways.
 Question: can you get out on a no ball in cricket Context: The Boy in the Striped Pyjamas (released as The Boy in the Striped Pajamas in the United States) is a 2008 drama film set in World War II, based on the novel of the same name by John Boyne. Directed by Mark Herman, produced by BBC Films and Heyday Films, and distributed by Miramax and Walt Disney Studios Motion Pictures, the film stars Vera Farmiga, David Thewlis, Asa Butterfield, and Jack Scanlon. It was released on 12 September 2008 in the United Kingdom.
 Question: is the boy in the striped pajamas a movie Context: In 2011, Philip Pullman remarked at the British Humanist Association annual conference that due to the first film's disappointing sales in the United States, there would not be any sequels made.
 Question: is there a part 2 to the golden compass Context: Most wine racks are designed to allow a wine to be stored on its side. The thinking behind this orientation is that the cork is more likely to stay moist and not dry out if it is kept in constant contact with the wine. Some wineries package their wines upside down in the box for much the same reason. Research in the late 1990s suggested that the ideal orientation for wine bottles is at a slight angle, rather than completely horizontal. This allows the cork to maintain partial contact with the wine in order to stay damp but also keeps the air bubble formed by a wine's ullage at the top rather than in the middle of the bottle if the wine is lying on its side. Keeping the ullage near the top, it has been argued, allows for a slower and more gradual oxidation and maturation process. This is because the pressure of the air bubble that is the ullage space rises and falls depending on temperature fluctuation. When exposed to higher temperatures the bubble's pressure increases (becomes positive relative to the air outside of the bottle), and if the wine is tilted at an angle, this compressed gas will diffuse through the cork and not harm the wine. When the temperature falls the process reverses. If the wine is completely on its side then this action will eject some wine through the cork. Through this ``breathing'' which can result from variations in temperature, oxygen may be repeatedly introduced into the bottle and as a result can react with the wine. An appropriate and constant temperature is therefore preferred. Additionally, oxidation will occur more rapidly at higher temperatures and gases dissolve into liquids faster the lower the temperature.
