 Question: can you have a heart attack from laughing Context: Just minutes before the ship started its final plunge, Smith was still busy releasing Titanic's crew from their duties; he went to the Marconi operators room and released Junior Marconi Officer Harold Bride and senior wireless operator John ``Jack'' Phillips from their duties. He then carried out a final tour of the deck, telling crew members: ``Now it's every man for himself.'' At 2:10 a.m., Steward Edward Brown saw the captain approach with a megaphone in his hand. He heard him say ``Well boys, do your best for the women and children, and look out for yourselves.'' He saw the Captain walk onto the bridge alone. This was the last reliable sighting of Smith. A few minutes later Trimmer Samuel Hemming found the bridge apparently empty. Five minutes later, the ship disappeared beneath the ocean. Smith perished that night along with around 1,500 others, and his body was never recovered.
 Question: did captain of titanic go down with ship Context: For nearly all models of induction cooktops, a cooking vessel must be made of, or contain, a ferrous metal such as cast iron or some stainless steels. The iron in the pot concentrates the current to produce heat in the metal. If the metal is too thin, or does not provide enough resistance to current flow, heating will not be effective. Most induction tops will not heat copper or aluminum vessels because the magnetic field cannot produce a concentrated current; ``all metal'' induction tops use much higher frequencies to overcome that effect. Any vessel can be used if placed on a suitable metal disk which functions as a conventional hotplate.

 Question: do you have to register to vote in america Context: Reduction in flow caused by dams, diversions, water for thermoelectric power stations, and evaporation losses from reservoirs -- the latter of which consumes more than 15 percent of the river's natural runoff -- has had severe ecological consequences in the Colorado River Delta and the Gulf of California. Historically, the delta with its large freshwater outflow and extensive salt marshes provided an important breeding ground for aquatic species in the Gulf. Today's desiccated delta, at only a fraction of its former size, no longer provides suitable habitat, and populations of fish, shrimp and sea mammals in the gulf have seen a dramatic decline. Since 1963, the only times when the Colorado River has reached the ocean have been during El Niño events in the 1980s and 1990s.
