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: At the time of the explosion, there were 126 crew on board; seven were employees of BP, 79 of Transocean, there were also employees of various other companies involved in the operation of the rig, including Anadarko, Halliburton and M-I SWACO. Eleven workers were presumed killed in the initial explosion. The rig was evacuated, with injured workers airlifted to medical facilities. After approximately 36 hours, Deepwater Horizon sank on 22 April 2010. The remains of the rig were located resting on the seafloor approximately 5,000 ft (1,500 m) deep at that location, and about 1,300 ft (400 m) (quarter of a mile) northwest of the well.
 Question: is the deepwater horizon still on the ocean floor Context: In older generation diesel-engine vehicles, unlike in a gasoline-engine vehicle, for a 'cold start' the operator did not simply turn the key to the ``start'' position and have the engine immediately start. Instead, the operator activated the glow plug(s) for a time first. Early diesels used the 'Thermostart' type glowplug in the inlet manifold. These take 20 seconds to achieve working temperature and the vehicle operator had to manually time (or guess) when the 20 seconds had elapsed. With in-cylinder glow plugs, technological improvements included a warning light on the dash to indicate how long the preheating should last. The preheating phase was also made to be automatically activated when the operator turned the key to the ``on'' position for a long duration; the glowplug relay switches the glowplugs on, and a light (see picture at right) on the instrument cluster illuminates. This process is called ``pre-heating'' or ``glowing''. Many modern diesels automatically activate their glow plugs when the operator unlocks the vehicle or opens the door to the car, thus simplifying the process and shortening the time the operator has to wait before the engine will start. According to Bosch: ``Older engines with Thermostart manifold plugs used a glow period of up to 20 seconds whereas more modern engines use around a 6 to 8 second heat period and provide after glow at a reduced voltage.''
 Question: do glow plugs stay on all the time Context: In 2011, the state adopted a ``modified open primary''. Individual citizens may vote for any candidate, and the top two candidates regardless of party will advance to the general election. The Presidential election is exempt from this voting method as it is a contest for delegates rather than a direct election for an office.
 Question: can you vote in the california primary as an independent Context: Based on a mark in an interior chamber naming the work gang and a reference to fourth dynasty Egyptian Pharaoh Khufu, Egyptologists believe that the pyramid was built as a tomb over a 10 to 20-year period concluding around 2560 BC. Initially at 146.5 metres (481 feet), the Great Pyramid was the tallest man-made structure in the world for more than 3,800 years. Originally, the Great Pyramid was covered by casing stones that formed a smooth outer surface; what is seen today is the underlying core structure. Some of the casing stones that once covered the structure can still be seen around the base. There have been varying scientific and alternative theories about the Great Pyramid's construction techniques. Most accepted construction hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.
