 Question: can you have a heart attack from laughing Context: Fort Bliss is a United States Army post in the U.S. states of New Mexico and Texas, with its headquarters located in El Paso, Texas. Named in honor of LTC William Bliss (1815-1853), a mathematical genius who was the son-in-law of President Zachary Taylor, Ft. Bliss has an area of about 1,700 square miles (4,400 km); it is the largest installation in FORSCOM (United States Army Forces Command) and second-largest in the Army overall (the largest being the adjacent White Sands Missile Range). The portion of the post located in El Paso County, Texas, is a census-designated place with a population of 8,591 as of the time of the 2010 census. Fort Bliss provides the largest contiguous tract (1,500 sq mi or 3,900 km) of restricted airspace in the Continental United States, used for missile and artillery training and testing, and at 992,000 acres boasts the largest maneuver area (ahead of the National Training Center, which has 642,000 acres).
 Question: is there a military base in el paso texas Context: The reactions are due to collisions of reactant species. The frequency with which the molecules or ions collide depends upon their concentrations. The more crowded the molecules are, the more likely they are to collide and react with one another. Thus, an increase in the concentrations of the reactants will usually result in the corresponding increase in the reaction rate, while a decrease in the concentrations will usually have a reverse effect. For example, combustion will occur more rapidly in pure oxygen than in air (21% oxygen).
 Question: are chemical reactions limited by the availability of reactants Context: In the 1994 TV documentary Hocus Pocus: Begin the Magic, and on the film's Blu-ray release, producer David Kirschner said he came up with the idea for the film one night. He and his young daughter were sitting outside and his neighbor's black cat strayed by. Kirschner invented a tale of how the cat was once a boy who was changed into a feline three hundred years ago by three witches.
 Question: is hocus pocus based on a true story Context: Lake Tahoe never freezes. Since 1970, it has mixed to a depth of at least 1,300 ft (400 m) a total of 6 or 7 times. Dissolved oxygen is relatively high from top to bottom. Analysis of the temperature records in Lake Tahoe has shown that the lake warmed (between 1969 and 2002) at an average rate of 0.015 °C per year. The warming is caused primarily by increasing air temperatures, and secondarily by increasing downward long-wave radiation. The warming trend is reducing the frequency of deep mixing in the lake, and may have important effects on water clarity and nutrient cycling.
