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: After the LAPD's establishment of its own SWAT team, many law enforcement agencies across the United States established their own specialized units under various names. Gates explained in his autobiography Chief: My Life in the LAPD that he neither developed SWAT tactics nor the associated and often distinctive equipment; but that he supported the underlying concept, tried to empower his people to develop it, and generally lent them moral support.
 Question: is there a swat team in every city Context: The cohesion-tension theory is a theory of intermolecular attraction that explains the process of water flow upwards (against the force of gravity) through the xylem of plants. It was proposed in 1894 by John Joly and Henry Horatio Dixon. Despite numerous objections, this is the most widely accepted theory for the transport of water through a plant's vascular system based on the classical research of Dixon-Joly (1894), Askenasy (1895), and Dixon (1914,1924).

 Question: does treason carry the death penalty in england Context: Graham's law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight. Thus, if the molecular weight of one gas is four times that of another, it would diffuse through a porous plug or escape through a small pinhole in a vessel at half the rate of the other (heavier gases diffuse more slowly). A complete theoretical explanation of Graham's law was provided years later by the kinetic theory of gases. Graham's law provides a basis for separating isotopes by diffusion--a method that came to play a crucial role in the development of the atomic bomb.
 Question: is there a relationship between molecular weight and diffusion rate Context: The man is passed by two container ships, which do not see him, despite his use of signaling flares. He drifts out of the shipping lane with no food or water. On the eighth day, he writes a letter, puts it in a jar, and throws it in the ocean as a message in a bottle. Later that night, he sees a light in the distance. He tears pages from his journal along with charts to create a signal fire. The fire grows out of control and consumes his raft. He falls into the water and allows himself to sink. Underwater, he sees the hull of a boat with a search light approaching his burning raft. He swims towards the surface to grasp an outstretched hand.
