 Question: can you have a heart attack from laughing Context: After the LAPD's establishment of its own SWAT team, many law enforcement agencies across the United States established their own specialized units under various names. Gates explained in his autobiography Chief: My Life in the LAPD that he neither developed SWAT tactics nor the associated and often distinctive equipment; but that he supported the underlying concept, tried to empower his people to develop it, and generally lent them moral support.
 Question: is there a swat team in every city Context: McG signed on to direct as the first two films were among his favorites, and he had even cast Robert Patrick (who played the T-1000) in his films. Though he was initially unsure about ``flogging a dead horse,'' he felt the post-apocalyptic setting allowed the film to be different enough so as not to be just an inferior sequel. The idea that events in Terminator 2: Judgment Day and Terminator 3: Rise of the Machines altered the future allowed them to be flexible with their presentation of the futuristic world. McG met with the series' co-creator James Cameron, and, although he neither blessed nor denigrated the project, Cameron told the new director he had faced a similar challenge when following Ridley Scott's Alien with Aliens. He maintained two elements of the previous films; that John is an outsider to the authorities, and someone of future importance is being protected, and in this film, it is Kyle Reese.
 Question: is terminator salvation a prequel to the terminator Context: To maintain lactation, a dairy cow must be bred and produce calves. Depending on market conditions, the cow may be bred with a ``dairy bull'' or a ``beef bull.'' Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as a breeding bull or sold and used for veal or beef. Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is approximately nine months. Newborn calves are removed from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf.
 Question: do cows only produce milk when they have babies Context: Generally, American football games last much longer than 80-minute rugby league matches. Because the field is reset after each tackle in American football, it is much slower-paced than the more hectic rugby league, in which play stops for only as long as it takes the tackled player to get back to his feet and return the ball to play. Another major difference is that only the player with possession of the ball may be interfered with in rugby league; defending players interfering with any other attacking player (and vice versa) will incur a penalty. Passing in the two sports also differs: while backward passing is common to both sports, in American football players are allowed to throw the ball forward in certain situations whereas in rugby league forward passing is always illegal. Rugby league players have to kick the ball or run it forward to advance it downfield. To score a try or touchdown in rugby league, the player has to push the ball directly onto the ground once in the try zone, whereas in American football the player has to simply cross the line. American football also requires its players to use a large amount of protective equipment, including helmets, gloves and padding around the body, whereas protective clothing is much more minimal in rugby league, usually amounting to light padding (if any) and soft head gear (hard helmets being illegal). The rugby pitch and American football field are both similar in size with a pitch being 100 meters while a football field is 100 yards.
