Facebook is a for-profit online social media and social networking service. The Facebook website was launched on February 4th, 2004 by Mark Zuckerberg, along with fellow Harvard College students and roommates. Since 2006, anyone age 13 and older has been allowed to become a registered user of Facebook though variations exist in minimum age requirement, depending on applicable local laws.
Over 25 million people in the Uk use Facebook. That’s 45% of population! And on average, each user spends over six hours a month on Facebook. Though not the highest this is a considerable number. Is Facebook is a dangerous obsession or just harmless fun? Seventeen-year-old Bethan has written on her blog about what it was like to stop using Facebook. I think I am a Facebook addict. I log on to Facebook everyday to chat to my friends real friends and loads of online friends. Sometimes I have ten conversations going at the same time. I upload photos and update my Facebook profile all the time. But recently I’ve started to feel worried if I am offline for more than a few hours. And then last week I forgot to meet a real friend because I was online! I’ve realised I could have a problem. So I’ve decided to give it up for a while. I found it really hard. Facebook and my friends demanded to know why I had left. I spent the first few evenings wondering what everyone was chatting on Facebook. I even phoned a couple of friends to find out. The fourth night I wasn’t quite so bad. I actually concentrated on my homework better and I had more time to watch my TV programmes. And I spoke to my friends during the day at school. At the end of the first week, I reactivated my account, I think Facebook is fun and it’s useful for posting messages to friends and sharing photos. But I’ll try not to spend so much time on it in the future.

The history of clinic nutrition, or the study of the relationship between health and how the body takes in and utilizers food substances, can be divided into four distinct eras: the first began in the nineteenth century and extended into the early twentieth century when it was recognized for the first time that food contained constituents that were essential agents. Near the end of this era, research studies demonstrated that rapid weight loss was associated with nitrogen imbalance and could only be rectified by providing adequate protein associate with certain foods.
The second era was initiated in the early decades of the twentieth century and might be called "the vitamin period". Vitamins came to be recognized in foods, endeficiency syndromes were described. As vitamins became recognized as essential food constituents necessary for health, it became tempting to suggest that every disease and condition for which there had been no previous effective treatment might be responsive to vitamin therapy. At the point in time, medical schools started to become more interested in having their curricula integrate nutritional therapies in medicine. Reckless claims were made for effects of vitamins that went far beyond what could actually be achieved from the use of them.
In the third era of nutritional history in the early 1950's to mid-1960's, vitamin therapy began to fall into disrepute. Concomitant with this, nutrition education in medical schools also became less popular. It was just a decade before this that many drug companies had found their vitamins sales skyrocketing and were quick to supply practicing physicians with generous samples of vitamins and literature extolling the virtue of supplementation for a variety health-related conditions. Expectations as to the success of vitamins in disease control were exaggerated. As is known in retrospect, vitamin and mineral therapies are much less effective when applied to health-crisis conditions that when applied to long-term problems of nutrition that lead chronic health problem.

Not very long ago, when people needed to find a job, there were several possible steps. They might begin with a look through the classified ads in the newspaper. They could go to the personnel office at various companies and fill out an application, or they could go to an employment agency. They could even find out about a job opening through word-of-mouth - from another person who had heard about it.
These days, job hunting is more complicated. The first step is to determine what kind of job you want (which sounds easier than it is) and make sure that you have the right education for it. Rapid changes in technology and science are creating many professions that never existed until recently. It is important to learn about them because one might be the perfect profession for you. The fastest- growing areas for new jobs are in computer technology and health services. Jobs in these fields usually require specific skills, but you need to find out exactly which degrees are necessary. For example, it may be surprising to learn that in the sciences, an M.S. is more marketable than a Ph.D! In other words, there are more jobs available for people with a Master of Science degree than for people with a doctorate (however, people who want to do research still need a Ph.D.) How do people learn about "hot" new professions? How do they discover their "dream job"? Many people these days go to a career counselor. In some countries, job hopping has become so common that career counseling is now "big business". People sometimes spend large amounts of money for this advice. In Canada and the United States, high school and college students often have access to free vocational counseling services on campus. There is even a career organization, the Five O'Clock Club, which helps members to set goals. Members focus on this question: what sort of person do you want to be years from now? The members then plan their career around that goal. All career counselors - private or public - agree on one basic point: it is important for people to find a career that they love. Everyone should be able to think, "I'm having such a good time. I can't believe they're paying me to do this.”

Insects’ lives are very short and they have many enemies, but they must survive long enough to breed and perpetuate their kind. The less insect-like they look, the better their chance of survival. To look "inedible" by resembling or imitating plants is a deception widely practiced by insects. Mammals rarely use this type of camouflage, but many fish and invertebrates do.
The stick caterpillar is well named. It is hardly distinguishable from a brown or green twig. This caterpillar is quite common and can be found almost anywhere in North America. It is also called "measuring worm" or "inchworm." It walks by arching its body, then stretching out and grasping the branch with its front feet then looping its body again to bring the hind feet forward. When danger threatens, the stick caterpillar stretches its body away from the branch at an angle and remains rigid and still, like a twig, until the danger has passed.
Walking sticks, or stick insects, do not have to assume a rigid, twig-like pose to find protection; they look like inedible twigs in any position. There are many kinds of walking sticks, ranging in size from the few inches of the North American variety to some tropical species that may be over a foot long. When at rest their front legs are stretched out, heightening their camouflage. Some of the tropical species are adorned with spines or ridges, imitating the thorny bushes or trees in which they live.
Leaves also seem to be a favorite object for insects to imitate. Many butterflies can suddenly disappear from view by folding their wings and sitting quietly among the foliage that they resemble.
