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: Each Triple Crown race is open to both colts and fillies. Although fillies have won each of the individual Triple Crown races, none has won the Triple Crown itself. Despite attempts to develop a ``Filly Triple Crown'' or a ``Triple Tiara'' for fillies only, no set series of three races has consistently remained in the public eye, and at least four different configurations of races have been used. Two fillies won the series of the Kentucky Oaks, the Pimlico Oaks (now the Black-Eyed Susan Stakes), and the Coaching Club American Oaks, in 1949 and 1952, but the racing press did not designate either accomplishment as a ``triple crown''. In 1961, the New York Racing Association created a filly triple crown of in-state races only, but the races changed over the years. Eight fillies won the NYRA Triple Tiara between 1968 and 1993.
 Question: did a filly ever win the triple crown Context: The peripheral nervous system (PNS) is one of the two components of the nervous system, the other part is the central nervous system (CNS). The PNS consists of the nerves and ganglia outside the brain and spinal cord. The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body. Unlike the CNS, the PNS is not protected by the vertebral column and skull, or by the blood--brain barrier, which leaves it exposed to toxins and mechanical injuries. The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve (cranial nerve II), along with the retina. The second cranial nerve is not a true peripheral nerve but a tract of the diencephalon. Cranial nerve ganglia originated in the CNS. However, the remaining ten cranial nerve axons extend beyond the brain and are therefore considered part of the PNS. The autonomic nervous system is an involuntary control of smooth muscle and glands. The connection between CNS and organs allows the system to be in two different functional states: sympathetic and parasympathetic.
 Question: is spinal cord part of peripheral nervous system Context: In older generation diesel-engine vehicles, unlike in a gasoline-engine vehicle, for a 'cold start' the operator did not simply turn the key to the ``start'' position and have the engine immediately start. Instead, the operator activated the glow plug(s) for a time first. Early diesels used the 'Thermostart' type glowplug in the inlet manifold. These take 20 seconds to achieve working temperature and the vehicle operator had to manually time (or guess) when the 20 seconds had elapsed. With in-cylinder glow plugs, technological improvements included a warning light on the dash to indicate how long the preheating should last. The preheating phase was also made to be automatically activated when the operator turned the key to the ``on'' position for a long duration; the glowplug relay switches the glowplugs on, and a light (see picture at right) on the instrument cluster illuminates. This process is called ``pre-heating'' or ``glowing''. Many modern diesels automatically activate their glow plugs when the operator unlocks the vehicle or opens the door to the car, thus simplifying the process and shortening the time the operator has to wait before the engine will start. According to Bosch: ``Older engines with Thermostart manifold plugs used a glow period of up to 20 seconds whereas more modern engines use around a 6 to 8 second heat period and provide after glow at a reduced voltage.''
