 Question: can you have a heart attack from laughing Context: The special exception which exists in the Criminal Justice Act 1988 (Sec. 139) for folding knives (pocket knives) with blades less than 3 inches (76mm) long, is another ``common sense'' measure accepting that some small knives are carried for general utility; This exemption however only applies to folding knives without a locking mechanism. The wording of the Criminal Justice Act does not mention locking and so the definition of ``folding pocket knife'' was settled through case law. In the Crown Court appeal of Harris v. DPP (1992) and the Court of Appeal case of R. v Deegan (1998) the ruling that 'folding' was intended to mean 'non-locking' was upheld. As the only higher court in England and Wales to the Court of Appeal is the Supreme Court, the only way the decision in R. v. Deegan could be overturned is by a dissenting ruling by the Supreme Court or by Act of Parliament.
 Question: is it legal to carry a pocket knife in england Context: Although not identical, the 7.62×51mm NATO and the commercial .308 Winchester cartridges are similar enough that they can be loaded into rifles chambered for the other round, but the Winchester .308 cartridges are typically loaded to higher pressures than 7.62×51mm NATO cartridges. Even though the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) does not consider it unsafe to fire the commercial round in weapons chambered for the NATO round, there is significant discussion about compatible chamber and muzzle pressures between the two cartridges based on powder loads and wall thicknesses on the military vs. commercial rounds. While the debate goes both ways, the ATF recommends checking the stamping on the barrel; if one is unsure, one can consult the maker of the firearm.
 Question: is the 308 the same as 7.62 x51 Context: Deforestation in the United States is an ongoing environmental issue that attracts protests from environmentalists. Prior to the arrival of European-Americans, about one half of the United States land area was forest, about 1,023,000,000 acres (4,140,000 km) estimated in 1630. Recently, the Forest Service reported total forestation as 766,000,000 acres (3,100,000 km) in 2012. The majority of deforestation took place prior to 1910 with the Forest Service reporting the minimum forestation as 721,000,000 acres (2,920,000 km) around 1920. The forest resources of the United States have remained relatively constant through the 20th century.
