 Question: can you have a heart attack from laughing 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.
 Question: is the egr valve part of the engine Context: Conventional baseball wisdom suggests that, when a pitcher and a hitter pitch or bat with the same hand, the pitcher typically has the advantage. This especially holds true for left-handed pitchers, as lefties are less common in a major-league lineup than righties. As a result, the most common use of the lefty-righty switch is when a right-handed pitcher is facing a left-handed batter. The manager of the defensive team will sometimes go to the bullpen, especially in close games where a reliever has already entered the game, and pull out a left-handed specialist to face the left-handed batter. The new pitcher will then attempt to get the batter out. Whether he succeeds or fails, the pitcher will often be replaced after the at-bat.
 Question: are right handed batters better against left handed pitchers Context: Creme eggs are available annually between 1 January and Easter Day. In the UK in the 1980s, Cadbury made Creme Eggs available year-round but sales dropped and they returned to seasonal availability.
 Question: can you buy cadbury creme eggs all year Context: A regular octagon is a closed figure with sides of the same length and internal angles of the same size. It has eight lines of reflective symmetry and rotational symmetry of order 8. A regular octagon is represented by the Schläfli symbol (8). The internal angle at each vertex of a regular octagon is 135° ( 3 π 4 (\displaystyle \scriptstyle (\frac (3\pi )(4))) radians). The central angle is 45° ( π 4 (\displaystyle \scriptstyle (\frac (\pi )(4))) radians).
 Question: are all sides of an octagon the same size Context: The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate. In the human skeleton, it consists of 80 bones and is composed of six parts; the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column. The axial skeleton together with the appendicular skeleton form the complete skeleton. Another definition of axial skeleton is the bones including the vertebrae, sacrum, coccyx, ribs, and sternum.
