Context: Death from laughter is a rare form of death, usually resulting from cardiac arrest or asphyxiation, caused by a fit of laughter. Instances of death by laughter have been recorded from the times of ancient Greece to the modern day.
 Question: can you have a heart attack from laughing Context: The bullsnake (Pituophis catenifer sayi) is a large non-venomous colubrid snake. It is currently considered a subspecies of the gopher snake (Pituophis catenifer).
 Question: are gopher snakes and bull snakes the same Context: Muhammad III, or Sidi Muhammad ibn Abdallah, came to power in 1757 and ruled until his death in 1790. Prior to his reign, Morocco had experienced 30 years of internecine battles, instability and turmoil. During the 33 years Sidi Muhammad ruled he transformed the politics, the economy and the society, putting development of international trade high on his agenda and restoring power to the sultanate. This served to quickly bring respect to Morocco on the international scene. Central to his pursuit of international trade was the negotiation of agreements with foreign commercial powers. He actively began seeking one with the United States well before the war with Great Britain was settled in 1783, finally got America's attention in 1784, and warmly welcomed Thomas Barclay's arrival to negotiate in 1786. The treaty signed by Barclay and the sultan, then by Jefferson and Adams, was ratified by the Confederation Congress in July 1787. It has withstood transatlantic stresses and strains for more than 232 years, making it the longest unbroken treaty relationship in United States history.
 Question: is the treaty of peace and friendship still valid Context: Toilet paper when used with a toilet roll holder with a horizontal axle parallel to the floor and also parallel to the wall has two possible orientations: the toilet paper may hang over (in front of) or under (behind) the roll; if perpendicular to the wall, the two orientations are right-left or near-away. The choice is largely a matter of personal preference, dictated by habit. In surveys of US consumers and of bath and kitchen specialists, 60--70 percent of respondents prefer over.
 Question: is there a correct way to hang toilet paper Context: When synthesizing new DNA, DNA polymerase can add free nucleotides only to the 3' end of the newly forming strand. This results in elongation of the newly forming strand in a 5'--3' direction. No known DNA polymerase is able to begin a new chain (de novo); it can only add a nucleotide onto a pre-existing 3'-OH group, and therefore needs a primer at which it can add the first nucleotide. Primers consist of RNA or DNA bases (or both). In DNA replication, the first two bases are always RNA, and are synthesized by another enzyme called primase. Helicase and topoisomerase II are required to unwind DNA from a double-strand structure to a single-strand structure to facilitate replication of each strand consistent with the semiconservative model of DNA replication.
