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 Reservation Against Cancellation (RAC) is a type of ticket that can be sold for travel on the Indian Railways. Although it ensures certainty of travel, it does not guarantee a berth. A berth will be allocated to the person who reserves an RAC ticket if passengers who already have a confirmed ticket do not turn up before the train departure or get their confirmed ticket cancelled. A berth is split into 2 seats for 2 RAC ticket holders. If there's any last minute cancellations, or if any quota allocations remain unsold, or if any confirmed ticket holders are given a free upgrade (more later), an RAC ticket holder is given the empty berth, the other RAC ticket holder can then convert the 2 seats into a berth.
 Question: can i travel if my ticket is rac Context: Modern dishes intended for home television use are generally 43 cm (18 in) to 80 cm (31 in) in diameter, and are fixed in one position, for Ku-band reception from one orbital position. Prior to the existence of direct broadcast satellite services, home users would generally have a motorised C-band dish of up to 3 m in diameter for reception of channels from different satellites. Overly small dishes can still cause problems, however, including rain fade and interference from adjacent satellites.
 Question: does the size of a satellite dish matter Context: Microscopically, there are differences between the neurons and tissue of the central nervous system and the peripheral nervous system. The central nervous system is divided in white and gray matter. This can also be seen macroscopically on brain tissue. The white matter consists of axons and oligodendrocytes, while the gray matter consists of neurons and unmyelinated fibers. Both tissues include a number of glial cells (although the white matter contains more), which are often referred to as supporting cells of the central nervous system. Different forms of glial cells have different functions, some acting almost as scaffolding for neuroblasts to climb during neurogenesis such as bergmann glia, while others such as microglia are a specialized form of macrophage, involved in the immune system of the brain as well as the clearance of various metabolites from the brain tissue. Astrocytes may be involved with both clearance of metabolites as well as transport of fuel and various beneficial substances to neurons from the capillaries of the brain. Upon CNS injury astrocytes will proliferate, causing gliosis, a form of neuronal scar tissue, lacking in functional neurons.
 Question: are neurons part of the central nervous system Context: South Carolina is a ``shall issue'' concealed carry permit state. No permit is required to purchase rifles, shotguns, or handguns. South Carolina also has ``Castle Doctrine'' legal protection of the use of deadly force against intruders into one's home, business, or car. It is unlawful to carry a firearm onto private or public school property or into any publicly owned building except interstate rest areas without express permission. Open carry of a handgun is not allowed (long guns are allowed), but no permit is required to carry a loaded handgun in the console or glove compartment of a car. As of 3 June 2016, states with which South Carolina has reciprocity are: Alaska, Arizona, Arkansas, Florida, Georgia, Idaho (enhanced permit only), Kansas, Kentucky, Louisiana, Michigan, Missouri, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, South Dakota (enhanced permit only), Texas, Tennessee, Virginia, West Virginia, and Wyoming. South Carolina only recognizes resident permits from the states with which it has reciprocity; non-resident permits from those states will not be honored. South Carolina does issue a CCW permit to a non-resident from a non-reciprocal state only if the non-resident owns real property in South Carolina as per Title 23 Chapter 31 Article 4 Section 23-31-210
