 Question: can you have a heart attack from laughing Context: Sockeye salmon (Oncorhynchus nerka), also called red salmon, kokanee salmon, or blueback salmon, is an anadromous species of salmon found in the Northern Pacific Ocean and rivers discharging into it. This species is a Pacific salmon that is primarily red in hue during spawning. They can grow up to 84 cm (2 ft 9 in) in length and weigh 2.3 to 7 kg (5.1--15.4 lb). Juveniles remain in freshwater until they are ready to migrate to the ocean, over distances of up to 1,600 km (990 mi). Their diet consists primarily of zooplankton. Sockeye salmon are semelparous, dying after they spawn. Some populations, referred to as kokanee, do not migrate to the ocean and live their entire lives in freshwater.
 Question: is sockeye salmon the same as red salmon Context: The black eagle is a large but slender eagle, at about 65 to 81 cm (26 to 32 in) in length and 148 to 182 cm (4 ft 10 in to 6 ft 0 in) in wingspan. Despite its large appearance (it is one of the largest eagles in its range), known weights are relatively modest, at between 1,000 and 1,600 g (2.2 and 3.5 lb), about half the weight of the partially sympatric mountain hawk-eagle, the latter being of a similar total length. Adults have all-black plumage, with a yellow bill base (cere) and feet. The wings are long and pinched in at the innermost primaries giving a distinctive shape. The tail shows faint barring and upper tail covers paler. When perched the wing tips reach till or exceed the tail tip. The wings are held in a shallow V (wings just above the horizontal plane) in flight. Seen on hot afternoons, scouring the treetops for a nest to maraud, this bird is easily spotted by its jet black colour, large size, and a 'characteristic' slow flight, sometimes just above the canopy.
 Question: is there such a thing as a black eagle Context: A passport stamp is a rubber stamp inked impression received in one's passport upon entering or exiting a country. Passport stamps may occasionally take the form of sticker stamps, such as entry stamps from Japan. Depending on nationality, a visitor may not receive a stamp (unless specifically requested), such as an EU/EFTA citizen travelling to an EU/EFTA country, Albania or Macedonia. Most countries issue exit stamps in addition to entry stamps. A few countries issue only entry stamps, including Australia, Canada, United States, New Zealand, Ireland, the United Kingdom, and El Salvador. Hong Kong, Macau, and Israel do not stamp passports upon entry nor exit, but issue landing slips instead. Visas may also take the form of passport stamps.
