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: Immediately after Ben Silverman was named co-chairman of NBC's entertainment division in 2007, he asked Greg Daniels to create a spin-off of The Office. Daniels co-created Parks and Recreation with Michael Schur, who had been a writer on The Office. The two spent months considering ideas for the new series and debating whether to make it a stand-alone show rather than a spin-off. According to Daniels, they eventually abandoned the original spin-off plan because they ``couldn't find the right fit''. They considered a series about a local government official trying to rebuild a political career following a humiliating public spectacle. They eventually abandoned the idea, though it did end up being incorporated into the backstory for Ben Wyatt late in the second season. After Amy Poehler agreed to play the lead, they decided the show would revolve around an optimistic bureaucrat in small-town government.

 Question: is the cephalic vein considered a deep vein Context: The film, produced by Stan Rogow, was directed by Jim Fall from a screenplay by Susan Estelle Jansen, Ed Decter and John J. Strauss and filmed on location in Rome, Italy in the fall of 2002. All the series characters reprised their roles except for Lalaine (Miranda Sanchez), who left the series late in the second season to film the Disney Channel original movie You Wish! Her character was said to be on vacation with her family in Mexico City.
 Question: did they film the lizzie mcguire movie in rome Context: According to the theory of relativity, no information can travel faster than the speed of light in vacuum, but this does not mean that the refractive index cannot be lower than 1. The refractive index measures the phase velocity of light, which does not carry information. The phase velocity is the speed at which the crests of the wave move and can be faster than the speed of light in vacuum, and thereby give a refractive index below 1. This can occur close to resonance frequencies, for absorbing media, in plasmas, and for X-rays. In the X-ray regime the refractive indices are lower than but very close to 1 (exceptions close to some resonance frequencies). As an example, water has a refractive index of 6999999999740000000♠0.99999974 = 1 − 6993260000000000000♠2.6×10 for X-ray radiation at a photon energy of 6985480652946099999♠30 keV (0.04 nm wavelength).
