While still catching up to men in some spheres of modern life, women appear to be way ahead in at least one undesirable category. "Women are particularly susceptible to developing depression and anxiety disorders in response to stress compared to men," according to Dr. Yehuda, chief psychiatrist at New York’s Veteran’s Administration Hospital. Studies of both animals and humans have shown that sex hormones somehow affect the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions. In several of the studies, when stressed-out female rats had their ovaries (the female reproductive organs) removed, their chemical responses became equal to those of the males. Adding to a woman’s increased dose of stress chemicals, are her increased "opportunities" for stress. "It’s not necessarily that women don’t cope as well. It’s just that they have so much more to cope with," says Dr. Yehuda. "Their capacity for tolerating stress may even be greater than men’s," she observes," it’s just that they’re dealing with so many more things that they become worn out from it more visibly and sooner." Dr. Yehuda notes another difference between the sexes. "I think that the kinds of things that women are exposed to tend to be in more of a chronic or repeated nature. Men go to war and are exposed to combat stress. Men are exposed lo more acts of random physical violence. The kinds of interpersonal violence that women are exposed to tend to be in domestic situations, by, unfortunately, parents or other family members, and they tend not to be one-shot deals. The wear-and-tear that comes from these longer relationships can be quite devastating." Adeline Alvarez married at 18 and gave birth to a son, but was determined to finish college. "I struggled a lot to get the college degree. I was living in so much frustration that that was my escape, to go to school, and get ahead and do better." Later, her marriage ended and she became a single mother. "It’s the hardest thing to take care of a teenager, have a job, pay the rent, pay the car payment, and pay the debt. I lived from paycheck to paycheck." Not everyone experiences the kinds of severe chronic stresses Alvarez describes. But most women today are coping with a lot of obligations, with few breaks, and feeling the strain. Alvarez’s experience demonstrates the importance of finding ways to diffuse stress before it threatens your health and your ability to function. Dr. Yehuda’s research suggests that women

A.need extra doses of chemicals to handle stress.
B.have limited capacity for tolerating stress.
C.are more capable of avoiding stress.
D.are exposed to more stress.

In his autobiography, Darwin himself speaks of his intellectual powers with extraordinary modesty. He points out that he always experienced much difficulty in expressing himself clearly and concisely, but (46)【he believes that this very difficulty may have had the compensating advantage of forcing him to think long and intently about every sentence, and thus enabling him to detect errors in reasoning and in his own observations.】He disclaimed the possession of any great quickness of apprehension or wit, such as distinguished Huxley. (47)【He asserted, also, that his power to follow a long and purely abstract train of thought was very limited, for which reason he felt certain that he never could have succeeded with mathematics.】His memory, too, he described as extensive, but hazy. So poor in one sense was if that he never could remember for more than a few days a single date or a line of poetry. (48)【On the other hand, he did not accept as well founded the charge made by some of his critics that, while he was a good observer, he had no power of reasoning.】This, he thought, could not be true, because the Origin of species is one long argument from the beginning to the end, and has convinced many able men. NO one, he submits, could have written it without possessing some power of reasoning. He was willing to assert that I have a fair share of invention, and of common sense or judgment, such as every fairly successful lawyer or doctor must have, but not, I believe, in any higher degree. (49)【He adds humbly that perhaps he was superior to the common run of men in noticing things which easily escape attention, and in observing them carefully. 】Writing in the last year of his life, he expressed the opinion that in two or three respects his mind had changed during the preceding twenty or thirty years. Up to the age of thirty or beyond it poetry of many kinds gave him great pleasure. Formerly, too, pictures had given him considerable, and music very great, delight. In 1881, however, he said: Now for many years I cannot endure to read a line of poetry. I have also almost lost my taste for pictures or music. (50)【Darwin was convinced that the loss of these tastes was not only a loss of happiness, but might possibly be injurious to the intellect, and more probably to the moral character.】
