 Question: can you have a heart attack from laughing Context: When attending a school formal or prom, providing a corsage for a prom date signifies consideration and generosity, as the corsage is meant to symbolize and honor the person wearing it. Corsages are usually worn around a prom date's wrist; alternatively, they may be pinned on her dress or a modified nosegay can be carried in her hand. The colors of the flowers are usually chosen to complement the dress or to add color to the couple, creating a unifying look. Prom couples may wish to go together to choose the flowers for a custom-made corsage or boutonnière. Traditionally, the male presents a corsage or nosegay to the female as a gift, while the female would provide the boutonnière and pin it on the male's shirt or jacket.
 Question: do you have to get corsages at homecoming Context: In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. This dilutes the O in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce peak in-cylinder temperatures. NO is produced in a narrow band of high cylinder temperatures and pressures. Another primary benefit of external EGR valves on a spark ignition engine is an increase in efficiency, as charge dilution allows a larger throttle position and reduces associated pumping losses.

This can include simultaneously employing hand gestures, movement, orientation of the fingers, arms or body, and facial expressions to convey a speaker's ideas. Sign languages often share significant similarities with their respective spoken language, such as American Sign Language (ASL) with American English. Grammar and sentence structure, however, may vary to encourage efficiency and fluidity in speaking. It is important to note that just because a spoken language is intelligible transnationally, such as English in the United States and the United Kingdom, does not mean that the sign languages from those regions are as well; ASL and British Sign Language (BSL) were formed independently and are therefore not mutually intelligible.
 Question: is english and spanish sign language the same Context: Because of the unusual format, several of the historically strongest men's national teams have unimpressive Olympic records. Uruguay won the tournament in their first two attempts, in 1924 and 1928, their only appearances before they qualified for the 2012 edition, after an 84-year absence. Argentina won silver twice (1928 and 1996) before the 2004 tournament, but its appearance in Athens, in which it won the first gold medal (the second was won in Beijing in 2008), was only their seventh overall (the eighth has been in 2016). Brazil's silver medals in the 1984, 1988 and 2012 editions were the best they had achieved until 2016's gold, and since professional athletes were allowed to compete, they failed to qualify in 1992 and 2004. Italy has only won the Olympic title once, in 1936, although it has also won two bronzes, and has the highest number of appearances in the tournament, at 15, with their last qualify in 2008. France has won the Olympic title only once (in 1984) and has failed to qualify since 1996. Germany's best result (before 2016 edition) was a single bronze medal, in 1988 (as West Germany), and the reunified team did not make an Olympic appearance until 2016, where they won silver. Spain has won the gold medal only once, in 1992. It has also won 2 silver medals (in 1920 and 2000) but has failed to qualify several times.
