My parents ran a small restaurant in Seattle. It was open twenty-four hours a day, six days a week. And my first real job, when I was six years old, was 36 the diners’ shoes. My father had done it when he was young, so he taught me 37 to do it well, telling me to 38 to shine the shoes again if the customer wasn’t 39 .
I was proud of working in the restaurant 40 I was also working for the good of the family. But my father 41 said that I had to meet certain standards(标准) to be part of the team. I 42 to be on time, hard-working, and polite to the 43 . I was 44 paid for the work I did at the restaurant. One day I made the mistake of suggesting to Dad that he 45 give me $10 a week. He said, “OK. How about you paying me for three meals a day you have here? And for the times you bring in your friends 46 free soft drinks?” He 47 the amount of money I owed him, about $40 a week.
I remember returning to Seattle after being 48 in the US Army for about two years. I had just been promoted（升职） to Captain at that time. And full of pride, I walked into my parents’ restaurant, but the 49 thing Dad said was, “How about your 50 up tonight?” I couldn’t 51 my ears! I am an officer in the Army! But 52 didn’t matter. As far as Dad was concerned, I was just 53 member of the team. I reached for the mop(拖把).Working for Dad has taught me that the devotion(奉献) to a 54 is above all. It has nothing to do with 55 that team is for a family restaurant or the US Army.

Parents who smoke often open a window or turn on a fan to clear the air for their children, but experts now have identified a related threat to children's health that isn't as easy to get rid of: third-hand smoke。
That's the term being 1 to describe the invisible yet poisonous mixture of gases and particles(颗粒) clinging(依附) to smokers' hair and 2 , not to mention cushions and carpeting, that stays long after second-hand smoke has cleared from a room. The remaining 3 heavy metals, carcinogens(致癌物) and even radioactive materials that young children can get on their hands and take in, 4 if they're crawling or playing on the floor。
Doctors from MassGeneral Hospital for Children in Boston coined the term "third-hand smoke" to 5 these chemicals in a new study that 6 on the risks they pose to infants and children. The study was published in the 7 issue of the journal Pediatrics。
"Everyone knows that second-hand smoke is bad, 8 they don't know about this," said Dr. Jonathan P. Winickoff, the lead author of the study and an assistant professor of pediatrics at Harvard Medical School。
"When their kids are 9 the house, they might smoke. Or they smoke in the car. Or they strap(用带子捆扎) the kid in the car seat in the back and crack the window and 10 , and they think it's okay because the second-hand smoke isn't getting to their 11 . We needed a term to describe these tobacco toxins that aren't12 ."
The study reported on 13 toward smoking in 1,500 households across the United States. It found that the vast majority of both smokers and nonsmokers were 14 that second-hand smoke is harmful to children. Some 95 percent of nonsmokers and 84 percent of smokers 15 with the statement that "inhaling smoke from a parent's cigarette can 16 the health of infants and children"。
But 17 fewer of those surveyed were aware of the 18 of third-hand smoke. Since the term is so new, the researchers asked people if they agreed with the statement that "breathing air in a room 19 where people smoked yesterday can harm the health of infants and children"。
Only 65 percent of nonsmokers and 43 percent of smokers agreed with that 20 , which researchers interpreted as acknowledgement of the risks of third-hand smoke。

Unhappy people glue（使粘牢） themselves to the television 30 percent more than happy people.
The finding, announced on Thursday, 1 from a survey of nearly 30,000 American adults conducted between 1975 and 2006 as part of the General Social Survey.
2 happy people reported watching an 3 of 19 hours of television per week, unhappy people reported 25 hours a week. The results held even after 4 into account education, income, age and marital status.
In addition, happy individuals were more socially 5 , attended more religious services, voted more and6 a newspaper more often than their less-chipper（没有精神的） counterparts.
The researchers are not sure, though, whether unhappiness7 more television-watching or more viewing leads to unhappiness.
In fact, people say they like watching television: Past research has shown that when people watch television they8 it. In these studies, participants reported that on a9 from 0 (dislike) to 10 (greatly enjoy), TV-watching was nearly an 8.
But perhaps the high from watching television doesn't10 .
"These conflicting data11 that TV may provide viewers with short-run12 , but at the expense of long-term malaise(精神欠爽)," said researcher John Robinson, a sociologist at the University of Maryland, College Park.
In this case, even the happiest campers could turn into Debbie-downers if they continue to13 at the TV. The researchers suggest that over time, television-viewing14 push out other activities that do have more lasting15 . Exercise and sex come to mind, as do parties and other forms of socialization known to have psychological benefits.
Or, maybe television is simply a refuge(慰藉物) for people who are already16 .
"TV is not judgmental 17 difficult, so people with18 social skills or resources for other activities can engage in it," Robinson and UM colleague Steven Martin write in the December issue of the journal Social Indicators Research.
They add, "19 , chronic unhappiness can be socially and personally debilitating（使人衰弱的） and can interfere with work and most social and personal activities, but even the unhappiest people can click a remote and be passively20 by a TV."
The researchers say follow-up studies are needed to tease out the relationship between television and happiness.

It seems parents have long been right. Going to bed early is key to getting enough sleep and helping adolescents feel on top of the world, a new study reported.
A 1 of sleep among youngsters may 2 depression and suicidal (自杀的)thoughts, according to the study by the Columbia University Medical Center.
"Our results are 3 with the theory that inadequate sleep is a risk factor for depression, working with other 4 and protective factors through multiple possible causal pathways to the development of this 5 disorder," said lead author James Gangwisch.
" 6 quality sleep could therefore be a preventative measure against 7 and a treatment for depression," he added in the study 8 in the Friday issue of Sleep magazine.
The study followed the nightly habits of some 15,659 college and high-school students, and 9 those who consistently went to bed 10 midnight had a 24 percent higher risk of depression than those who turned in before 10:00 pm.
Night owls（夜猫子）also ran a 20 percent 11 risk of battling suicidal thoughts, the study added.
The American Academy of Sleep Medicine 12 that adolescents should sleep at least nine hours or more a night. Those who were tucked in before 10:00 pm reported they slept13 about eight hours and 10 minutes.
But that amount of sleep 14 significantly for those in bed after midnight.
And adolescents who slept five hours or less a night were 71 percent more 15 to suffer depression and 48 percent more16 becoming suicidal, the study said.
"It is a common perception and societal 17 that adolescents do not need as much sleep as pre-adolescents, yet studies suggest that adolescents may 18 require more sleep," said Gangwisch.
"Studies have found that adolescents do not go to bed 19 enough to make up for earlier school start times, and transitions to earlier school start times have been shown to be 20 with significant sleep deprivation（剥夺）. "

Don't blame genes for aging facial skin. A new study of twins suggests you can 1 those coarse(粗糙的) wrinkles, brown or pink spots, and dilated(膨胀的) blood vessels on too much time in the sun, smoking, and being overweight.
Because twins share genes, but may have2 exposures to environmental factors, studying twins allows an, "opportunity to control for genetic susceptibility(敏感性)," Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and colleagues3 in the latest issue of Archives of Dermatology.
Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is4 more to environment and lifestyle than5 factors.
But when it 6 skin cancer, the researchers say their findings support previous reports that 7 environment and genes affect skin cancer risk.
Baron's team 8 facial skin of 130 twins, 18 to 77 years old, who lived9 in the northern Midwest and Eastern regions of the U.S. who were10 the Twins Days Festival in Ohio in August 2002.
At this time, each of the twins also11reported how their skin burned or tanned12 sunscreen(防晒霜), their weight, and their history of skin cancer, smoking, and alcohol drinking.
The study group 13 of 52 fraternal and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status. Identical(同卵的) twins share all of their genes and fraternal twins share only about half.
From these data, the researchers14 strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental15
16 contrast, sunscreen use and drinking alcohol appeared correlated with 17 skin damage.
Baron and colleagues say the current findings, which highlight ties between facial 18 and potentially avoidable 19 factors -- such as smoking, being overweight, and 20 overexposure to the sun's damaging rays -- may help motivate people to minimize these risky behaviors.

Cutting meat production and consumption by 30 percent would help to reduce carbon emissions(排放) and improve health in the most meat-loving nations, scientists said on Wednesday.
Using prediction models, British and Australian researchers1 that improving efficiency, increasing carbon capture and2 fossil fuel dependence in farming would not be enough to3 emissions targets.
But combining these steps4 a 30 percent reduction in livestock（家畜） 5 in major meat-producing nations and a similar6 in meat-eating, would lead to "substantial population health benefits" and cut emissions, they said.
The study found that in Britain, a 30 percent7 intake of animal-source saturated（饱和的） fat by adults would reduce the8 of premature（过早的） deaths from heart disease by some 17 percent -- equivalent to 18,000 premature deaths reduced in one year.
In Sao Paulo, Brazil, it could mean as9 as 1,000 premature deaths reduced in a year, they said.
10 the United Nations Food and Agricultural Organization, 18 percent of all greenhouse gas emissions are from meat production and experts say rising11 for meat, particularly in countries with growing economies, could12 livestock production up by 85 percent from 2000 levels13 2030.
The scientists said global action was needed to maximize the benefits of cutting meat production and14 , and that the environmental15 "may apply only in those countries that currently have high production levels."
The study was16 in The Lancet medical journal as part of a series in climate change and health17 the Copenhagen global climate summit scheduled next month.
In a second study, British scientists found that increased walking and cycling, and18 cars, would have a much greater impact on health19 low-emission vehicles in rich and middle-income countries.
Andrew Haines, director of the London School of Hygiene and Tropical Medicine and head of the research series, said delegates at Copenhagen needed "to understand the potential20 impacts of their plans."
