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.

In the United Kingdom, only the monarch has the power to declare war and peace, under the royal prerogative. There have been no declarations of war since the Second World War, though British Armed Forces have taken part in armed conflict on numerous occasions nonetheless.

 Question: is there a difference between 2stroke and 2-cycle oil Context: Aviation research during World War II led to the creation of the first rocket- and jet-powered aircraft. Several claims of breaking the sound barrier during the war subsequently emerged. However, the first recognized flight exceeding the speed of sound by a manned aircraft in controlled level flight was performed on October 14, 1947 by the experimental Bell X-1 research rocket plane piloted by Charles ``Chuck'' Yeager. The first production plane to break the sound barrier was an F-86 Canadair Sabre with the first 'supersonic' woman pilot, Jacqueline Cochran, at the controls. According to David Masters, the DFS 346 prototype captured in Germany by the Soviets, after being released from a B-29 at 32800 ft (10000 m), reached 683 mph (1100 km/h) late in 1945, which would have exceeded Mach 1 at that height. The pilot in these flights was the German Wolfgang Ziese.
 Question: can planes go faster than the speed of sound Context: On July 5, the ship California Star recorded winds of 35 mph (55 km/h) and a barometric pressure of 1,005.8 mb (30 inHg); consequently, the storm was upgraded into Tropical Storm Natalie. After passing through the Tres Marinas Islands just offshore, Natalie attained its peak intensity of 80 mph (130 km/h) (making Natalie a Category 1 hurricane on the present-day Saffir-Simpson Hurricane Wind Scale) and a peak pressure of 1,001 mb (29.6 inHg), though the Pacific hurricane database does not show the storm getting any stronger than 50 mph (80 km/h). The next day, July 7, the NFWC reported that Natalie made landfall near Mazatlan with winds of 50 mph (80 km/h) just before dissipating. No known impact was recorded.
 Question: has there ever been a hurricane named natalie Context: Typically, the patient fasts for ten or twelve hours before the blood is drawn for the test--this is particularly important for getting a useful blood glucose measurement. CMPs are also frequently performed on nonfasting patients, but the glucose level in those cases is not as useful. The following tests are then performed:
