Article: For centuries Stonehenge has mystified and enraptured archaeologists and visitors. So maybe it is not surprising that another monumental wonder from prehistory has been overlooked for so long - even though it is just a mile away. Experts have discovered an 'extraordinary' line of giant stones that dates back more than 4,500 years. The area around Stonehenge is littered with prehistoric sights but the 90 or more stones, lying 3ft underground, have only just been discovered by sophisticated radar equipment towed by radar equipment. The buried monoliths are each up to 15ft tall. Instead of being arranged in a circle as they are at Stonehenge, it is thought they once formed a long standing line. 'We are looking at one of the largest stone monuments in Europe and it has been under our noses for something like 4,000 years,' said Professor Vince Gaffney, from the University of Bradford, one of the archaeologists leading the research. 'It's truly remarkable. We don't think there's anything quite like this anywhere else in the world. This is completely new and the scale is extraordinary." Prof. Gaffney believes the stones may have been planted by the same people who built Stonehenge, but he doubts whether there is a direct link between the two monuments. These stones were placed along a steep slope, cut into a natural dry valley to form a C-shaped feature. Precisely why the stones were put there remains a mystery. The archaeologists believe that at some stage the stones were pushed over. This was not done to damage the monument but rather to preserve whatever it was about the stones that seemed so important. "There was a transformation in the landscape that we do not understand," Prof. Gaffney said. "The stones had significance. These were special places. Societies were organized, as with the great cathedrals, to create these things."
Answer: It is the largest stone monument all over the world.

Article: Science can't explain the power of pets,but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack,reduce loneliness and spread all-round good cheer. Any owner will tell you how much joy a pet brings.For some.an animal provides more comfort than a husband/wife.A 2002 study by Karen Allen of the State University of New York measured stress 1evels and blood pressure in people-half of them pet owners-while they performed 5 minutes of mental arithmetic or held a hand in ice water.Subjects completed the tasks alone,with a husband/wife,a close friend or with a pet.People with pets did it best.Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates.With pets in the room,people also made fewer math mistakes than when doing in front of other companions.It seems people feel more relaxed around pets,says Allen,who thinks it may be because pets don't judge. A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits.Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs;a separate group of 56 people without pets were put on a diet program.On average,people lost about 11 pounds,or 5% of their body weight.Their dogs did even better,losing an average of 12 pounds,more than 15%of their body weight.Dog owners didn't lose any more weight than those without dogs but,say researchers,got more exercise overall-mostly with their dogs--and found it worth doing.

Article: A job is more than a job,especially to the old. "It's not the money that matters,but the sense of self-worth."56-year-old Cbeng Wonlan said. So,every day Ms Cheng carries a bag of parcels,letters and documents and does her rounds in North Point. She's a courier Five years ago.Ms Cheng was a nurse at a private clinic. She had worked there for 30 years but was Jobless when the doctor migrated. It was difficult for her to find another job as a nurse. "People do not trust my ability when they learn how old I am,"she said. After two years of searching, she eventually found another nursing job. But then after two years,she quit Why? 'My colleagues were young and they didn't understand me because of my age. They often asked me 'You are so old what are you working for? I was very unhappy" She said. So while the rest of her family left for work,she was left to lonely boredom at home .Then her neighbours told her about Employee's Retraining Board(ERB)offering retraining courses for older people. These courses are specifically designed to encourage the older people back to work. "I was interested in courier work. I didn't think my age was a barrier because I was fit." She said .Upon graduating,Ms Cheng was offered a job by the Speeding Shuttle Courier Service Company. But then Ms Cheng was faced with a conflict:she was caught between honour and employment"I felt embarrassed about carrying and delivering letters and parcels." she said. It took Ms Cheng 24 hours to make up her mind:there was nothing wrong or embarrassing about doing the job. So she went off to work as a courier.
