Did you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent(聪明的) than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain consists of  “grey matter” and
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes. As white matter is the key to spatial(空间的) tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries: why men refuse to ask for directions … and women often need to!
The differences begin when fetuses(胎儿) are about mine weeks old, which can be seen in the action of children ad young as one. A boy would try to climb a barrier (障碍物) before him or push it down while a girl would attract help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors(祖先) ,among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.
If all this disappoints you, it shouldn’t. “The brain changes throughout our lives according to what we do with it.” says a biologist.

If people work to meet their needs, it would be good to know what these needs are. They are very simple. Dr. Maslow has suggested that people have only five needs. Everyone has them, and everyone spends his or her life trying to satisfy them. Although we may try to satisfy our needs in different ways, we all are trying to satisfy the same needs. In a way, it is these needs, which are common to all people that make us human. They seem to be a basic part of human nature.
The needs, which occur in the order shown below, can briefly be described as follows:
1. The Physiological Needs--Our needs for the things that keep our bodies alive – food, water, air, rest, elimination, etc. These needs come first. We must meet them or we will die.
2. The Safety Needs--First we need to stay alive, and then we need to be safe. There are two kinds of safety needs: the need to be physically safe and the need to be psychologically safe or secure.
3. The Belongingness Needs--Once we are alive and safe, we then try to satisfy our social need, a need to be with and accepted by other people. We discover our need for love.
4. The Esteem Needs--After our first three needs are fairly well met, we try to satisfy a fourth need. This is a need for recognition, respect, reputation. The need has two parts: self esteem(thinking well of ourselves) and the esteem of others.
5. The Self--Actualization Needs--The highest need of man is to actualize himself, to achieve his full potential, to become all that he might be. This need is one that no one ever satisfies completely, partly because we are too busy trying to satisfy our lower needs.
If Dr. Maslow is correct, those are the things we are after. Our work, rest, play--whatever we do--is done in an effort to meet one or more of those needs.
81. _____________

Over the last 70 years, researchers have been studying happy and unhappy people and finally found out ten factors that make a difference. Our feelings of well-being at any moment are determined to a certain degree by genes. However, of all the factors, wealth and age are the top two.
Money can buy a degree of happiness. But once you can afford to feed, clothe and house yourself, each extra dollar makes less and less difference.
Researchers find that, on average, wealthier people are happier. But the link between money and happiness is complex. In the past half-century, average income has sharply increased in developed countries, yet happiness levels have remained almost the same. Once your basic needs are met, money only seems to increase happiness if you have more than your friends, neighbors and colleagues.
“Dollars buy status, and status makes people feel better,” conclude some experts, which helps explain why people who can seek status in other ways－scientists or actors, for example－may happily accept relatively poorly-paid jobs.
In a research, Professor Alex Michalos found that the people whose desire－not just for money, but for friends, family, job, health－rose furthest beyond what they already had, tended to be less happy than those who felt a smaller gap(差距). Indeed, the size of the gap predicted happiness about five times better than income alone. “The gap measures just blow away the only measures of income.” Says Michalos.
Another factor that has to do with happiness is age. Old age may not be so bad. “Given all the problems of aging, how could the elderly be more satisfied?” asks Professor Laura Carstensen.
In one survey, Carstensen interviewed 184 people between the ages of 18 and 94, and asked them to fill out an emotions questionnaire. She found that old people reported positive emotions just as often as young people, but negative emotions much less often.
Why are old people happier? Some scientists suggest older people may expect life to be harder and learn to live with it, or they’re more realistic about their goals, only setting ones that they know they can achieve. But Carstensen thinks that with time running out, older people have learned to focus on things that make them happy and let go of those that don’t.
“People realize not only what they have, but also that what they have cannot last forever,” she says. “A goodbye kiss to a husband or wife at the age of 85, for example, may bring far more complex emotional responses than a similar kiss to a boy or girl friend at the age of 20.”
