Across the industrialized world, women still live 5 to 10 years longer than men. Among people over 100 years old, 85% are women, according to Tom Perls, founder of the New England Centenarian Study at Boston University and creator of the website LivingTo100. com. Time. com asks him why.
Why do women live longer than men?
One important reason is the big delay — and advantage — women have over men in terms of cardiovascular disease, like heart attack and stroke. Women develop these problems usually in their 70s and 80s, about 10 years later than men. For a long time, doctors thought the difference was due to estrogen. But studies have shown that this may not be the case, and now we know that giving estrogen to women post-menopause can actually be bad for them.
One reason for that delay in onset of cardiovascular disease could be that women are relatively iron-deficient compared to men — especially younger women, those in their late teens and early 20s — because of menstruation. Iron plays a very important part in the reactions in our cells that produce damaging free radicals, which glom onto cell membranes and DNA, and may translate into aging the cell. In fact, in our diets, red meat is the main source of iron, and lack of iron is probably one major reason that being vegetarian is healthy for you. There was a very good study looking at the intake of red meat and heart disease in Leiden in the Netherlands: in regions where people didn’t eat red meat, those populations had half the rate of heart attack and stroke compared to the populations that did eat red meat.
21. According to the passage, what is true about Tom Perls, founder of the New England Centenarian Study?
22. According to Tom Perls, which of the following might be an important reason that women live longer than men?
23. According to the passage, when do men usually develop cardiovascular disease?
24. Compared to men, which of the following is women relatively deficient in?
25. What might the next paragraph discuss?

A、In their 50s and 60s.
B、In their 60s and 70s.
C、In their 70s and 80s.
D、In their 80s and 90s.
答案
B
解析
细节题。文中说到女性开始罹患心脑血管疾病的年龄在70多岁到80多岁,比男性晚10年,由此可计算得知男性开始患同类疾病的年纪在60多岁到70多岁。因此本题答案为B。
