1. Of the more than 1000 cycling deaths each year, three fourth are caused by head injuries. Half of those killed are school-age children. One study concluded that wearing a bike helmet can reduce the risk of head injury by 85 percent. In an accident, a bike helmet absorbs the shock and cushions the head."Bike Helmet: Unused Lifesavers"
Consumer Reports (May1990): 348.

According to Consumer Report (1990), deaths from cycling are accumulated to more than 1000 victims annually with 75 percent due to head injuries and 50 percent of those deceased are adolescent. The risk of injury to head can be lowered to almost 90 percent using head gear based on a research. The head gear is capable of cushioning the head and reduces the shock from a crash.

2. While the Sears Tower is arguably the greatest achievement in skyscraper engineering so far, it's unlikely that architects and engineers have abandoned the quests for the world's tallest building. The question is; just how high can a building go? Structural engineer William LeMessurier has designed a skyscraper nearly one-half mile high, twice as tall as the Sears Tower. And architect Robert Sobel claims that existing technology could produce a 500-story building. From Ron Bachman, "Reaching for the Sky." Dial (May 1990): 15.

Ron Bachman (1990) argued that architects and scientists are always on the mission to build a building even taller than Sears Tower which is considered the finest architecture. But the limitations of the height of buildings remain unknown. A skyscraper almost one-half mile high and double the height of Sears tower has been modelled by William LeMessurier and Robert Sobel proposed that a 500-story building could be engineered with the current brainpower and machine.

3. A key factor in explaining the sad state of American education can be found in over bureaucratization, which is seen in the compulsion to consolidate our public schools into massive factories and to increase to mammoth size our universities even in under populated states. The problem with bureaucracies is that they have to work hard and long to keep from substituting self-serving survival and growth for their original primary objective. Few succeed. Bureaucracies have no soul, no memory, no conscience. If there is a single stumbling block on the road to the future, it is the bureaucracy as we know it. Edward T. Hall, Beyond Culture, Anchor Publishing, 1977, p.219.

Edward T. Hall (1977) discussed that bureaucratization is the main factor of the degrading status of American education which combines the public institutions into enormous industrial units and to greatly expand the size of the tertiary institutions in less populated area. In bureaucratization, its primary objective is to work fruitlessly in order to survive. However, many failed because bureaucracies are cold and heartless. Bureaucracy is the only hindrance for future undertakings.
