Q29 Is a problem in a person's healthy maintenance system? A Man is performing substitution of an immunity system or a self-restoration system by the medicine, operation, etc. The whole human beings have made the resistance power which should originally exist decline as a result, and this becomes the situation that it cannot correspond by himself to an accident. The thing with many cancer patients also has a cause [ that there are many carcinogens ] in a civilized country in environment. But, it is supposed since immunity power is declining since there are many degrees depending on a medicine. coli bacillus poisoning etc. is many illnesses to a civilized country. It seems that this also has a cause in it being used to environment clean usually. Moreover, a cigarette is not exactly a medicine, either. The medicinal action which made nicotine the subject has various influences on a human body. And it has a bad influence on a human body like other medicines except improving a specific condition. The smoking person of a civilized country is under the environment which is immunity power, and is exposed to many carcinogens when having already undertaken the handicap. It lives in the house which dried the excrement of an animal, and people who are living a life which what the fly extorted is calm and eats it also civilization-ize certainly. It may also be the problem of time to come to suffer from food poisoning, if a thing is eaten, without these persons washing. And the disease rate of their cancer will also go up.
