Admittedly it is true that the increasingly rapid pace of life today has lead to an unutterable disarrangement in psychology and physiology of modern people and thus to some extent reduced the quality of human life, but one should not go too far to unduly exaggerate its negative effects. As a matter of fact, what the rapid life tempo benefits modern people is far much greater than its potential harms.
