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: Multiple citizenship, dual citizenship, multiple nationality or dual nationality, is a person's citizenship status, in which a person is concurrently regarded as a citizen of more than one state under the laws of those states. There is no international convention which determines the nationality or citizen status of a person. Citizenship status is defined exclusively by national laws, which can vary and can conflict. Multiple citizenship arises because different countries use different, and not necessarily mutually exclusive, criteria for citizenship. Colloquial speech refers to people ``holding'' multiple citizenship, but technically each nation makes a claim that a particular person is considered its national.
 Question: can a person hold more than two citizenships Context: The Homegrown Player Rule has been an initiative in England and the Premier League to allow for more domestic, English players to be a brought up from a younger age in hopes of creating more talented English players. Currently, the Premier League does not have a maximum restriction on the number of foreign players allowed on a team, but does require at least eight homegrown players. Greg Dyke, new chairman of the Football Association (FA), wants to implement much stronger regulation of foreign players. His intention is clear as stated in an op-ed piece so that England can win the 2022 World Cup in Qatar. Some of Dyke's propositions include: homegrown players in a top-flight 25-man first-team squad be increased from eight to 12 two of which must be brought up in the teams youth system, and also changing the definition of what it is to be a homegrown player. Currently, to be classified as homegrown one must be on an English team for at least three years before the age of twenty-one in which Dyke would like to reduce to eighteen years. This would mean a teenager would have to be with the club at a maximum age of fifteen and players are not allowed to move across national boundaries, even European Union boundaries, before 16. Meaning such that, if a foreign player joined an English youth academy at sixteen, in three years time he would be nineteen. Thus said player failing to qualify as a homegrown player due to the fact he would be older than eighteen.

 Question: is there a cure for rift valley fever 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.
