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: "Now stretch over your right leg!" my dance teacher yells over the music. "If it doesn't hurt, you're not trying hard enough. Hold that stretch for 30 seconds!" My dance teacher works hard to form us into the dancers we desire to be. In order for this to occur, we stretch hard a lot! Dancing is a real passion of many people, including me. I work hard to make myself better, and prove that I am good enough. Performing a dance routine is more than just a performance. Dancers tell stories when they dance. It is a way for us to express our personal feelings. Just letting go and letting your body move with the music can create your emotions. Dance tells us things that our mind secretly hides. "Get up and do it again! You need to keep your spirits up!" Even though I am completely worn out after my dances, I love to hear those words. It gives me a sense of relief knowing that I can again express my feelings out on the floor. "Practice makes perfect! Come on. We have a competition this weekend, and we need to work harder!" Competitions are the best possible example of fun. For a dancer, life cannot get better than competitions. The thrill of losing yourself onstage is a rush of energy rushing through your body! The feeling is unexplainable. As you sit there putting on your makeup, fixing your hair, and putting on your costume, the rush just gradually grows until it is ready to be released onstage. Finally the time comes to tell your story. Standing backstage waiting for your name to be called is one of the scariest moments. You are ready to show the world what you are capable of and what you have been perfecting for a while. Once your number is called, you walk out onstage. The applause at the end tells each dancer that their story has been received, and that the dance has been brought to life.
