Biologists believe that love is fundamentally a biological rather than a cultural construct, because the capacity for love is found in all human cultures and similar behavior is found in some other animals. In humans the purpose of all the desire is to focus attention on the raising of offspring. Children demand an unusual amount of parenting, and two parents are better than one. Love is a signal that both partners are committed, and makes it more likely that this commitment will continue as long as necessary for children to reach independence. But what does science have to say about the notion of love at first sight?
In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love, a dozen different part of brain work together to release chemicals that trigger feelings of euphoria, bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love.
Passionate love is rooted in the reward circuitry of the brain—the same area that is active when humans feel a rush from cocaine. In fact, the desire, motivations and withdrawals involved in love have a great deal in common with addiction. Its most intense forms tend to be associated with the early stages of a relationship, which then give way to a calmer attachment form of love one feels with a long term partner.
What all this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a second how attractive they find another person. This decision appears to be related to facial attractiveness, although men may favor women with waist-to-hip ratio of 0.7, no matter what their overall weight is. (This ratio may indicate a woman’s reproductive health.)
Another piece of evidence comes from work by a psychologist at Ben-Gurion University, who found in a survey that a small percentage (11%) of people in long-term relationships said that they began with love at first sight. In other words, in some couples the initial favorable impressions of attractiveness triggered love which sustained a lengthy bond. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers.
One might also assume that if a person is looking for a partner with traits that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships.

Being less than perfectly well-dressed in a business setting can result in a feeling of great discomfort that may well require treatment to eliminate. And the sad truth is that “clothing mismatches” on the job can ruin the day of the person who is wearing the inappropriate attire(着装)—and the people with whom he or she comes in contact.
Offices vary when it comes to dress codes. Some businesses have very high standards for their employees and set strict guidelines for office attire, while others maintain a more relaxed attitude. However, it is always important to remember that no matter what your company’s attitude is regarding what you wear, you are working in a business environment and you should dress properly. Certain items may be more appropriate for evening wear than for a business meeting, just as shorts and a T-shirt are better suited for the beach than for an office environment. Your attire should reflect both your environment and your position. A senior vice president has a different image to maintain than that of a secretary or sales assistant. Like it or not, you will be judged by your personal appearance.
This is never more apparent than on “dress-down days”, when what you wear can say more about you than any business suit ever could. In fact, people will pay more attention to what you wear on dress-down days than on “business professional ” days. Thus, when dressing in “business casual” clothes, try to put some good taste into your wardrobe choices, recognize that the “real” definition of business casual is to dress just one notch(等级) down from what you would normally wear of business-professional attire days.
Remember, there are borders between your career and our social life. You should dress one way for play and another way when you mean business. Always ask yourself where you are going and how other people will be dressed when you get there. Is the final destination the opera, the beach, or the office? Dress properly and you will discover the truth in the principle that clothes make the man—and the woman. When in doubt, always misjudge on the side of dressing slightly more traditionally than the situation demands.
