著名医学家、诺贝尔奖金获得者杜博斯断言:“现代人已经不那么需要对抗严寒天气、食物缺乏的窘境及其它伤害身体的危害。但他们必须应付的是时刻表、交通、噪音、拥挤、竞争及其它人为的紧张环境。驱车的路上交通受拥塞,承担的工作遭受挫折,对竞争的紧张应付和事业失败的痛苦,同配偶的争吵不休……这些紧张反应像细菌、病毒、营养不良或有害的理化因素一样,能够成为对人类健康的一种挑战。” Dobos, a famous medical scientist and Nobel laureate, asserted: “The modern people are less needy to deal with cold weather, lack of food and other harm to the body, but they have to deal with timetables, traffic, noise and crowding , Competition and other man-made stressful environments. Traffic congestion on the road to driving, setbacks in the work undertaken, the pain of competition and business failure, the sparring with spouses ... These nervous reactions are like bacteria, viruses, malnutrition Or harmful physical and chemical factors, can be a challenge to human health. ”
