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: If a set of sets is infinite or contains an infinite element, then its union is infinite. The powerset of an infinite set is infinite. Any superset of an infinite set is infinite. If an infinite set is partitioned into finitely many subsets, then at least one of them must be infinite. Any set which can be mapped onto an infinite set is infinite. The Cartesian product of an infinite set and a nonempty set is infinite. The Cartesian product of an infinite number of sets each containing at least two elements is either empty or infinite; if the axiom of choice holds, then it is infinite.
 Question: is the union of two infinite sets always an infinite set Context: In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. The congruence of opposite sides and opposite angles is a direct consequence of the Euclidean parallel postulate and neither condition can be proven without appealing to the Euclidean parallel postulate or one of its equivalent formulations.
 Question: does a parallelogram have to have equal sides Context: Packet filters act by inspecting the ``packets'' which are transferred between computers on the Internet. If a packet does not match the packet filter's set of filtering rules, the packet filter will drop (silently discard) the packet or reject it (discard it, and send ``error responses'' to the source). Conversely, if the packet matches one or more of the programmed filters, the packet is allowed to pass. This type of packet filtering pays no attention to whether a packet is part of an existing stream of traffic (i.e. it stores no information on connection ``state''). Instead, it filters each packet based only on information contained in the packet itself (most commonly using a combination of the packet's source and destination address, its protocol, and, for TCP and UDP traffic, the port number). TCP and UDP protocols constitute most communication over the Internet, and because TCP and UDP traffic by convention uses well known ports for particular types of traffic, a ``stateless'' packet filter can distinguish between, and thus control, those types of traffic (such as web browsing, remote printing, email transmission, file transfer), unless the machines on each side of the packet filter are both using the same non-standard ports.
 Question: when a firewall filters traffic the firewall drops the traffic Context: Prince Philip, Duke of Edinburgh (born Prince Philip of Greece and Denmark, 10 June 1921), is the husband and consort of Queen Elizabeth II.
