CHICAGO (Reuters) - Smoking not only can wrinkle(起皱纹) the face and turn it yellow -- it can do the same to the whole body, researchers reported on Monday.

The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body -- even skin protected from the sun.

"We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda Helfrich of the University of Michigan, who led the study, said in a statement.

"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years," Helfrich's team added in their report.

The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers Independent judges decided how wrinkled each person's skin was.

When skin is exposed to sunlight, notably the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich's team wrote.

Several previous studies have found that cigarette smoking contributes to premature(过早的)skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light.

The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels(血管)beneath the skin to constrict(紧缩), reducing blood supply to the skin.

Smoking can also damage the connective tissue that supports both the skin and the internal organs.

Q&A

Question: I have recently got a senior position within my company. One of my new tasks is to make monthly progress reports on my department in front of other senior officials. During my first meeting, I presented and then opened the floor to questions.   1.  My first reaction was to answer defensively. Later, I realized that I shouldn’t have felt that way. But how can I keep cool and effectively answer questions in this type of settings?

Answer: Congratulations on your new position! Presenting in front of your peers (同事) is a hard task in itself, and it becomes much more difficult when a question-and-answer period is required. Question-and-answer periods as a great way to clarify the message and strengthen key points.  2.

Speech—the act of uttering sounds to convey meaning—is a kind of human action. Like any other constantly repeated action, speaking has to be learned, but once it is learned, it becomes a generally unconscious and apparently automatic process.

As far as we can determine, human beings do not need to be forced to speak; most babies seem to possess a sort of instinctive drive to produce speech like noises. How to speak and what to say are another matter altogether. There actions are learned from the particular society into which the baby is born; so that, like all conduct that is learned from a society—from the people around us—speech is a patterned activity.

The meandering(漫目无地的)babble(咿呀学语)and chatter of a young child are eventually channeled by imitation into a few orderly grooves that represent the pattern accepted as meaningful by the people around him. Similarly, a child’s indiscriminate(不加分辨的)practice of putting things into his mouth becomes limited to putting food into his mouth in a certain way.

The sounds that a child can make are more varied and numerous than the sounds that any particular language uses. However, a child born into a society with a pattern of language is encouraged to make a small selection of sounds and to make these few sounds over and over until it is natural for him to make these sounds and not others.

A.not as varied as those used in language

A professor I have worked pretty closely with has been diagnosed with Stage 4 cancer. It has been devastating(悲惨的) for his family and heartbreaking for his students.

What made him extraordinary was not only that he was a rising star. He had only recently collected the highest honors for young researchers at the White House. We truly admire him—as someone put it, ‘He always has a smile and a kind word for everyone.” It is very hard to find someone who is extremely intelligent should be so nice a human being.

I decided that we needed him to know our attitude and also how we are all praying for his recovery. I bought him a simple card which read, ‘Healing thoughts and wishes coming your way.” I met all the students he worked closely with and got them to sign on it. Each student in his laboratory signed and also added a message. ‘We love you so much”, ‘We miss you! We need you back here—recover soon”… These were some of the messages that were written. Most of the students were really glad we were doing this and said it was a very good idea to give it to him.

He is still undergoing intense treatment, and along with his family is trying his best to stay optimistic and hopeful. I didn’t see a trace of self-pity or sadness when I met him last week. Instead, he paid attention to every word of my presentation and asked me several questions related to my work. I was amazed at how much he gave his 100% on that day in spite of being in pain because of chemotherapy( 化疗),he did not know if he even had another month to live. “I am trying to focus on staying positive, hoping to be back this summer,” he said.

Needless to say, I saw an expression of joy and hope on his face as he opened the card. He said he was truly touched to see the messages from the students he worked closely with.

There is one thing I learnt from last week: It is so important to tell people how much they mean to us and what an inspiration they are before it becomes too late.
