Most important, Heller found that the chromosomes could be twisted, turned, forced into new alignments. Since chromosomes carry the genetic material that controls growth and heredity, this maltreatment often kept cells from dividing, or caused mutations. Dr. Heller's waves are so specific that a change of frequency or pulsing can limit their effect to a single kind of cell, leaving slightly different cells unaffected. Since cancer cells differ from normal cells, there is a chance (which Dr. Heller does not want to talk about) that they can be damaged by radio waves that do not hurt healthy tissue...
...teachers, all too often, are trained in schools that offer substandard instruction, skimp courses in academic subjects in favor of courses on teaching method, give far too little practice teaching in actual classrooms.

Much of the prestige that once went with a big car disappeared as new prestige articles became popular. Many consumers were apt to pass up Detroit's wiles, instead spend their money for recreation, housing, travel, boats...
