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. Options: A They have lower blood pressure. B They become more patient. C They are less nervous. D They are in higher spirits. Answer: C They are less nervous. Question:

A pre-teen boy approached my car and asked me for money to help him and his mother stay in their hotel for an additional week. He stated that if they did not come up with $25 they would be _ that same evening. Having worked in social services before and having doubt about this, I asked why his mother hadn't applied for social services for assistance. The boy said that they needed to remain in their hotel for one more week until his grandmother, who lived out of town, could take them in. I gave the boy what I had -- $5. He thanked me and continued to wander the parking lot asking for help. I got my gas and drove away. Some weeks ago, a boy asked me for money and I told him I didn't have any though I did. Yet, I thought about it for a while and went looking for the boy to give him a dollar. But it seemed that he had disappeared into thin air. "This time," I thought, "I'll do it differently." I went to my bank and got an additional $20, then I returned to the gas station. The boy was still there. I observed him shyly approaching strangers who walked past him without notice. I pulled up and waved at the boy to come over. I handed him the $20 bill. He reached through my car window and gave me a huge hug. His hug told me all I needed to know -- that finally this kid could get out of the rain, the cold and the darkening skies and go inside where it was warm.

He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport (carry) them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein , in the province of Quebec in Canada. Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens; the rock breaks down into fine, soft, soapy fibres .
