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: A flare gun, also known as a Very pistol or signal pistol, is a large-bore handgun that discharges flares. The flare gun is used to create illumination for improved vision or as a distress signal. A flare gun can be used as a deadly weapon; however, that is not its intended function.
 Question: can a flare gun be used as a weapon Context: Any contestant who overbids is disqualified regardless of their opponent's result. A double overbid results in neither contestant winning a showcase. Since 1974, any contestant who comes within a specified amount from the actual retail price of their own showcase without going over wins both showcases. Until 1998, the amount was less than $100. In 1998, it became the current $250 or less.
 Question: can you still win both showcases on price is right Context: In humans, cold shock response is perhaps the most common cause of death from immersion in very cold water, such as by falling through thin ice. The immediate shock of the cold causes involuntary inhalation, which if underwater can result in drowning. The cold water can also cause heart attack due to vasoconstriction; the heart has to work harder to pump the same volume of blood throughout the body. For people with heart disease, this additional workload can cause the heart to go into arrest. Inhalation of water (and thus drowning) may result from hyperventilation. Some people are much better able to survive swimming in very cold water due to body or mental conditioning.
 Question: can cold water make you go into shock Context: A referendum on the political status of Puerto Rico was held in Puerto Rico on June 11, 2017. The referendum had three options: becoming a state of the United States, independence/free association, or maintaining the current territorial status. Those who voted overwhelmingly chose statehood by 97%; turnout, however, was 23%, a historically low figure. This figure is attributed to a boycott led by the pro-status quo PPD party.
 Question: did puerto rico vote to become a us state Context: The pressure-gradient force is the force which results when there is a difference in pressure across a surface. In general, a pressure is a force per unit area, across a surface. A difference in pressure across a surface then implies a difference in force, which can result in an acceleration according to Newton's second law of motion, if there is no additional force to balance it. The resulting force is always directed from the region of higher-pressure to the region of lower-pressure. When a fluid is in an equilibrium state (i.e. there are no net forces, and no acceleration), the system is referred to as being in hydrostatic equilibrium. In the case of atmospheres, the pressure gradient force is balanced by the gravitational force, maintaining hydrostatic equilibrium. In Earth's atmosphere, for example, air pressure decreases at altitudes above Earth's surface, thus providing a pressure gradient force which counteracts the force of gravity on the atmosphere.
