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: Fart lighting, also known as pyroflatulence or flatus ignition, is the practice of igniting the gases produced by human flatulence, often producing a flame of a blue hue, hence the act being known colloquially as a ``blue angel'', ``blue dart'', or in Australia, a ``blue flame''. The fact that flatus is flammable, and the actual combustion of it through this practice, gives rise to much humorous derivation. Other colors of flame such as orange and yellow are possible with the color dependent on the mixture of gases formed in the colon. In order to ``fire fart'', one must have a fart prepared in the anal cavity, and a lighter at the ready. Then they fart onto the lighter.

 Question: does clarithromycin cause a bad taste in the mouth Context: In 2004 a new range of Dr. Martens was launched in an attempt to appeal to a wider market, and especially young people. The shoes and boots were intended to be more comfortable, and easier to break in, and included some new design elements. Dr. Martens also began producing footwear again at the Cobbs Lane Factory in Wollaston, England in 2004. These products are part of the ``Vintage'' line, which the company advertises as being made to the original specifications. Sales of these shoes are low in comparison to those made in Asia, however; in 2010, the factory was producing about 50 pairs per day. In 2005, the R. Griggs company was given an award by the ``Institute for Turnaround'' for implementing a successful restructure.
 Question: are doc martens still made in the uk Context: With their righting reflex, cats often land uninjured. However, this is not always the case, since cats can still break bones or die from extreme falls. In a 1987 study, published in the Journal of the American Veterinary Medical Association, of 132 cats that were brought into the New York Animal Medical Center after having fallen from buildings, it was found that the injuries per cat increased depending on the height fallen up to seven stories, but decreased above seven stories. The study authors speculated that after falling five stories the cats reached terminal velocity and thereafter relaxed and spread their bodies to increase drag. However, critics of the study pointed out a survivorship bias in that instantly fatal falls were not included (as an already dead cat would not be taken to the vet), questioning the authors' conclusion that the injury rate declined for higher falls. A 2003 study of 119 cats concluded that ``Falls from the seventh or higher stories, are associated with more severe injuries and with a higher incidence of thoracic trauma.''
