 Question: can you have a heart attack from laughing Context: Hair color is the pigmentation of hair follicles due to two types of melanin: eumelanin and pheomelanin. Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color on the same person. Particular hair colors are associated with ethnic groups. Gray or white hair is associated with age.

Its dense forests support populations of large mammals, birds, and alpine species. The region is noted for its heavy snowfall. The park has an extensive network of trails, three campgrounds, and four backcountry huts and cabins. Due to the major transportation routes that bisect it, Glacier National Park sees large numbers of visitors.
 Question: are there glaciers in glacier national park canada Context: Generally, American football games last much longer than 80-minute rugby league matches. Because the field is reset after each tackle in American football, it is much slower-paced than the more hectic rugby league, in which play stops for only as long as it takes the tackled player to get back to his feet and return the ball to play. Another major difference is that only the player with possession of the ball may be interfered with in rugby league; defending players interfering with any other attacking player (and vice versa) will incur a penalty. Passing in the two sports also differs: while backward passing is common to both sports, in American football players are allowed to throw the ball forward in certain situations whereas in rugby league forward passing is always illegal. Rugby league players have to kick the ball or run it forward to advance it downfield. To score a try or touchdown in rugby league, the player has to push the ball directly onto the ground once in the try zone, whereas in American football the player has to simply cross the line. American football also requires its players to use a large amount of protective equipment, including helmets, gloves and padding around the body, whereas protective clothing is much more minimal in rugby league, usually amounting to light padding (if any) and soft head gear (hard helmets being illegal). The rugby pitch and American football field are both similar in size with a pitch being 100 meters while a football field is 100 yards.
 Question: is american football and rugby the same thing Context: In 2012, the U.S.-based group Defense Distributed disclosed plans to design a working plastic gun that could be downloaded and reproduced by anybody with a 3D printer. Defense Distributed has also designed a 3D printable AR-15 type rifle lower receiver (capable of lasting more than 650 rounds) and a variety of magazines, including for the AK-47. In May 2013, Defense Distributed completed design of the first working blueprint to produce a plastic gun with a 3D printer. The United States Department of State demanded removal of the instructions from the Defense Distributed website, deeming them a violation of the Arms Export Control Act. In 2015, Defense Distributed founder Cody Wilson sued the United States government on free speech grounds and in 2018 the Department of Justice settled, acknowledging Wilson's right to publish instructions for the production of 3D printed firearms.
