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: Over the 140 years of Major League Baseball history, and over 210,000 games played, there have been 23 official perfect games by the current definition. No pitcher has ever thrown more than one. The perfect game thrown by Don Larsen in game 5 of the 1956 World Series is the only postseason perfect game in major league history and one of only two postseason no-hitters. The first two major league perfect games, and the only two of the premodern era, were thrown in 1880, five days apart. The most recent perfect game was thrown on August 15, 2012, by Félix Hernández of the Seattle Mariners. There were three perfect games in 2012; the only other year of the modern era in which as many as two were thrown was 2010. By contrast, there have been spans of 23 and 33 consecutive seasons in which not a single perfect game was thrown. Though two perfect-game bids have gone into extra innings, no extra-inning game has ever been completed to perfection.
 Question: has there ever been a perfect game in the world series Context: Wood gasifiers can power either spark ignition engines, where 100% of the normal fuel can be replaced with little change to the carburation, or in a Diesel engine, feeding the gas into the air inlet that is modified to have a throttle valve, if it didn't have it already. On Diesel engines the Diesel fuel is still needed to ignite the gas mixture, so a mechanically regulated Diesel engine's ``stop'' linkage and probably ``throttle'' linkage must be modified to always give the engine a little bit of injected fuel, often under the standard idle per-injection volume. Wood can be used to power cars with ordinary internal combustion engines if a wood gasifier is attached. This was quite popular during World War II in several European, African and Asian countries, because the war prevented easy and cost-effective access to oil. In more recent times, wood gas has been suggested as a clean and efficient method to heat and cook in developing countries, or even to produce electricity when combined with an internal combustion engine. Compared to World War II technology, gasifiers have become less dependent on constant attention due to the use of sophisticated electronic control systems, but it remains difficult to get clean gas from them. Purification of the gas and feeding it into natural gas pipelines is one variant to link it to the existing refueling infrastructure. Liquefaction by the Fischer--Tropsch process is another possibility.
 Question: can a diesel engine run on wood gas 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.
