在产生抗体方面,妇女比男子优越,因此,妇女的病毒性和细菌性疾病的发病率较低。有一名病理学家认为,就免疫力来讲,妇女可能占有优势。出生时,男婴与女婴的比例120:100,但在16岁后,这个数字逐渐拉平,而且在此以后男性在相对数字上继续下降。尽管某些因素,如职业和生活方式,对此有影响,但男性对疾病的抵抗力较低,也许可以更好地解释妇女的寿命为什么要比男人平均长8岁的原故。
Women are superior to men in producing antibodies, and therefore women have a lower incidence of viral and bacterial diseases. One pathologist believes that women may have an advantage in terms of immunity. At birth, the ratio of baby boys to girls is 120: 100, but after the age of 16, the figure is gradually leveling off, and after that the number of males continues to decline in relative numbers. Although some factors, such as occupation and lifestyle, affect this, men are less resistant to disease and may be better able to explain why women have an average life expectancy of 8 years longer than men.
