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: is pine oil and turpentine the same thing Context: The film was originally released in 1977 with the title ``Star Wars''. The subtitles Episode IV and A New Hope were only added to the opening crawl in subsequent re-releases. Accounts differ as to when this designation was first added; some date the change at the theatrical re-release of April 10, 1981, while others place it much earlier at the re-release in July 1978. The retroactive addition of these subtitles was intended to bring the film into line with the introduction to its sequel, The Empire Strikes Back, which was released in 1980 bearing the designation ``Episode V''. It is uncertain if the introduction of an episodic naming convention was an indicator of Lucas's original intent, or if this was simply a later redraft of the narrative. According to some accounts, Lucas has claimed that he was discouraged by Twentieth Century Fox from using an episode number on a new film because it would confuse audiences. Gary Kurtz has stated that he and Lucas had originally considered using an episode number for Star Wars to emulate the chapter numbering used in the 1936 Flash Gordon installments, but they were uncertain whether they should designate it Episode III, IV or V. However, some of Lucas's early script drafts bear titles such as ``The Adventures of the Starkiller (Episode One): The Star Wars'' (1975) or ``The Adventures of Luke Starkiller as Taken from the Journal of the Whills: Saga One: Star Wars'' (1976). The Revised Fourth Draft of the script dated January 1975 acquired the subtitle ``Episode IV -- A New Hope -- from the Journal of the Whills'' when published in the 1979 book The Art of Star Wars.
 Question: was star wars a new hope always episode 4 Context: A 'light' symmetrical wing-clip will allow a bird to fly down and land safely while indoors. However such a clip may not prevent the bird from flying when outdoors, since lift is generated in proportion to wind speed. Many escaped birds which are recovered are found to have been clipped. So, while a light clip allows downward flight indoors, it does not prevent a bird gaining lift if it should escape outdoors. Conversely, a more severe clip will certainly render a bird flightless, but it increases the risk of injury if the bird falls and hits a hard surface. In addition to the physical effects of wing-clipping, there can be adverse behavioural effects. Birds use flight as an instinctive reflex action and as their first means of escaping any threat: they take to the air to fly upwards and away from the source of the threat; their fear then dissipates. Where this behaviour is prevented by wing-clipping, this innate reflex action is denied the bird, and its fear will not subside. This may cause behavioural problems for the afflicted bird. When a bird needs to reduce its speed during flight, it employs a 'reverse thrust' action by extending its wing at the wrist joint and using the drag of its primaries as air brakes. While the reduced function of the clipped bird's primaries prevent propulsion and therefore lift, this also reduces braking abilities, so clipped birds may crash-land at higher speeds than full-winged birds. Clipped birds should not be taken outdoors unrestrained, as even clipped birds have been known to fly away when spooked outdoors.
