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: The groundhog (Marmota monax), also known as a woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. It was first scientifically described by Carl Linnaeus in 1758. The groundhog is also referred to as a chuck, wood-shock, groundpig, whistlepig, whistler, thickwood badger, Canada marmot, monax, moonack, weenusk, red monk and, among French Canadians in eastern Canada, siffleur. The name ``thickwood badger'' was given in the Northwest to distinguish the animal from the prairie badger. Monax was a Native American name of the woodchuck, which meant ``the digger''. Young groundhogs may be called chucklings. Other marmots, such as the yellow-bellied and hoary marmots, live in rocky and mountainous areas, but the groundhog is a lowland creature. It is found through much of the eastern United States across Canada and into Alaska
 Question: is a woodchuck and a groundhog the same animal Context: Graham's law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight. Thus, if the molecular weight of one gas is four times that of another, it would diffuse through a porous plug or escape through a small pinhole in a vessel at half the rate of the other (heavier gases diffuse more slowly). A complete theoretical explanation of Graham's law was provided years later by the kinetic theory of gases. Graham's law provides a basis for separating isotopes by diffusion--a method that came to play a crucial role in the development of the atomic bomb.
 Question: is there a relationship between molecular weight and diffusion rate Context: A distinction is drawn in the US between professional doctorates and ``doctor's degree - research/scholarship'', with the latter being ``(a) Ph.D. or other doctor's degree that requires advanced work beyond the master's level, including the preparation and defense of a dissertation based on original research, or the planning and execution of an original project demonstrating substantial artistic or scholarly achievement.'' Internationally, US professional doctorates (which, unlike research doctorates, are not defined as requiring work beyond the master's level) are not generally considered to be doctoral level qualifications. The classification of ``Doctor's degree - other'' also exists for doctorates that do not meet the definition of either professional doctorates or research doctorates.
 Question: is a professional degree higher than a phd 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.
