It was fifteen past nine as Marie hurried into the office building where she was going to work.
Her bus had inched along through heavy morning traffic, making her a few minutes late for her very
first job. She decided to start out half an hour earlier the next day.
Once inside the lobby, she had to stand at the elevators and wait several minutes before she
could get on one going to the sixth floor. When she finally reached the office marked "Smith Enter-
prises" , she knocked at the door nervously and waited. There was no reply. She tapped on the door
again, but still there was no answer. From inside the next office, she could hear the sound of
voices, so she opened the door and went in.
Although she was sure it was the same office she had been in two weeks before when she had
the interview with Mr. Smith, it looked quite different now. In fact, it hardly looked like an office
at all. The employees were just standing around chatting and smoking. In the front of the room,
somebody must have just told a good joke, she thought, because there was a loud burst of laughter as
she came in. For a moment she had thought they were laughing at her.
Then one of the men looked at his watch, clapped his hands and said something to the others.Quickly they all went to their desks and, in a matter of seconds, everyone was hard at work. No one paid any attention to Marie. Finally she went up to the man who was sitting at the desk nearest to the door and explained that this was her first day in the office. Hardly looking up from his work, he told her to have a seat and wait for Mr. Smith, who would arrive at any moment. Then Marie realized that the day's work in the office began just before Mr. Smith arrived. Later she found out that he lived in Connecticut and came into Manhattan on the same train every morning, arriving in the office at 9:35,so that his staff knew exactly when to start working.

For most of us, dieting is a frustrating fact of life. With so much conflicting nutritional information about, it can be difficult to tell which weight-loss strategies really work. Let' s start by discounting these confusing myths.
1. All calories are created equal
What you eat, not how much, is the main factor behind weight gain, according to research.Calories from fat pack on the pounds. The reason: during digestion, the body burns many more calories metabolizing protein and carbohydrates than it does metabolizing fat.
2. Desserts are taboo
Cakes, pies and ice cream can sensibly be worked into a diet, the expert says. Moderation is the key. CVt down on other meals if you'll be eating out at a restaurant known for its rich sweets.Or indulge, but take only a few bites.
3. Fast foods are forbidden
A plain hamburger on a bun is still a healthful choice. So is grilled chicken or a green salad with low-cal dressing. But watch out for French fries, milkshakes and batter-dipped chicken or fish.
4. Fasting is the fastest diet
Some studies suggest that drastically reducing calorie intake switches the body into a " starvation
mode", which conserves calories and decreases your metabolic rate. The more frequently you deprive yourself of food, the better your body may get at storing calories. So, in the long run, repeated fasting may actually undermine your weight-loss efforts.
5. To keep weight off, simply watch what you eat .
According to experts, exercise combined with dieting ensures weight Joss better than dieting alone does. Experts also agree that sticking with regular, moderate exercise is more important that occasional vigorous workouts are. Obesity-researcher Kelly Brownell encourages patients to make a series of small physical efforts: taking the stairs instead of the elevator and parking the car far from where you are going and walking.
Most important, before getting caught up in dietary myths, let good sense shape your eating habits. Your body will thank you for it.

Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment,so it includes employees and the self-employed. Labor is one of the country's resources which can be combined with other resources to produce the goods and services required by the community. .
Though the size of the workforce relies greatly on the size of the total population,there are several other aspects which also affect it. The age distribution of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work,then the available workforce would be lower than if there were an evenly spread age distribution.If the population grows rapidly from natural increase,i. e. the number of births greatly exceeds the number of deaths,then as a total population increases, the proportion in the workforce declines.
Sometimes a population is described as aging,which means that the birth rate is either falling or growing very slowly,and as people retire from the workforce, there are inadequate numbers of young people entering it to take place of those who are leaving it. The population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid increase in births or a falling birth rate. '
The age distribution of the population has several important influences on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce,this raises the problem of the ability of the economy to provide a reasonable level of social services to the retired group. If the aged are to be cared for in special homes or hotels,finance must be available for that purpose. If the size of the workforce is small relative to the total population,then the government tax receipts are relatively low and either the govemment has less money available to it or the workforce members have to be taxed more heavily.
