 Question: can you have a heart attack from laughing Context: A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.
 Question: is li-ion the same as lithium Context: The chemical elements can be broadly divided into metals, metalloids and nonmetals according to their shared physical and chemical properties. All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metals; and have at least one basic oxide. Metalloids are metallic-looking brittle solids that are either semiconductors or exist in semiconducting forms, and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, coloured or colourless appearance; are brittle when solid; are poor conductors of heat and electricity; and have acidic oxides. Most or some elements in each category share a range of other properties; a few elements have properties that are either anomalous given their category, or otherwise extraordinary.
 Question: is low conductivity used to tell metals from nonmetals Context: Pepsi Zero Sugar contains 69 milligrams of caffeine per 355ml (12 fl oz). Diet Pepsi contains 36 milligrams of caffeine per 355ml (12 fl oz).
 Question: are diet pepsi and pepsi max the same Context: July 19 is the 200th day of the year (201st in leap years) in the Gregorian calendar. There are 165 days remaining until the end of the year.

It does not include decisions that have been abrogated by subsequent constitutional amendment or by subsequent amending statutes.
 Question: can the supreme court overturn a previous ruling Context: A mule is the offspring of a male donkey (jack) and a female horse (mare). Horses and donkeys are different species, with different numbers of chromosomes. Of the two F1 hybrids (first generation hybrids) between these two species, a mule is easier to obtain than a hinny, which is the offspring of a female donkey (jenny) and a male horse (stallion).
