 Question: can you have a heart attack from laughing 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: Meanwhile, Crassus has found Varinia and Spartacus's newborn son and has taken them prisoner. He is disturbed by the idea that Spartacus can command more love and loyalty than he can and hopes to compensate by making Varinia as devoted to him as she was to her former husband. When she rejects him, he furiously seeks out Spartacus (whom he recognizes from having watched him at Batiatus' school) and forces him to fight Antoninus to the death. The survivor is to be crucified, along with all the other men captured after the great battle. Spartacus kills Antoninus to spare him this terrible fate. The incident leaves Crassus worried about Spartacus's potential to live in legend as a martyr. In other matters, he is also worried about Caesar, whom he senses will someday eclipse him.
 Question: did spartacus die at the end of the movie Context: An unlisted public company is a public company that is not listed on any stock exchange. Though the criteria vary somewhat between jurisdictions, a public company is a company that is registered as such and generally has a minimum share capital and a minimum number of shareholders. Each stock exchange has its own listing requirements which a company (or other entity) wishing to be listed must meet. Besides not qualifying to be listed, a public company may choose not to be listed on a stock exchange for a number of reasons, including because it is too small to qualify for a stock exchange listing, does not seek public investors, or there are too few shareholders for a listing. There is a cost to the listed entities, in the listing process and ongoing costs as well as in compliance costs such as the maintenance of a company register.
