Because of their biological significance, amino acids are important in nutrition and are commonly used in nutritional supplements, fertilizers, and food technology.

Because of their relatively large mass, + 2 electric charge and relatively low velocity, alpha particles are very likely to interact with other atoms and lose their energy, so their forward motion is effectively stopped within a few centimeters of air.

Because of the tortuous terrain in places, villages and towns in the mountains — to which travel via motorized vehicles are of little use — are still located in the high Andes of Argentina, Bolivia, Peru, and Ecuador.

Because reported AIDS cases in Africa and other parts of the developing world include a larger proportion of people who do not belong to Duesberg's preferred risk groups of drug addicts and male homosexuals, Duesberg writes on his website that " There are no risk groups in Africa, like drug addicts and homosexuals ," However, many studies have addressed the issue of risk groups in Africa and concluded that the risk of AIDS is not equally distributed.

Because the number of players in a LARP is usually larger than in a tabletop role-playing game, and the players may be interacting in separate physical spaces, there is typically less of an emphasis on tightly maintaining a narrative or directly entertaining the players, and game sessions are often managed in a more distributed manner.
