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: Watching a child struggle to breathe during as asthma attack is frightening for any parent. So it is only natural that most moms and dads will try just about anything, including spending a lot of money -to keep an attack at bay. Trouble is, more than half of parents are trying strategies that simply do not work and wasting hundreds of dollars in the process. According to Dr. Machael Cabana, a pediatrician at the prefix = st1 /UniversityofMichigan's C.S. Mott Children's Hospital, who led the study, one of the most common mistakes was to buy mattress cover to protect against dust mites for a child whose asthma instead was made by plant pollen . Many of those parents then neglected to do what would have helped a lot more; shut the windows to keep pollen out. Another was using a humidifier for a child who was allergic to dust mites; a humidifier tends to be a place where dust mites like to breed. With those allergies, a dehumidifier works better. Worst of all was the number of smokers with asthmatic children who didn't even try to quit or at least limit themselves to smoking outdoors rather than just moving to another room or the garage. Many smoking parents purchased expensive air filters that have what Cabana called " questionable utility. " Part of the problem, Dr. Caban and his colleagues believe, is that parents are bombarded by television ads that encourage them to buy products such as air and carpet fresheners, ionizers and other remedies that are often expensive but medically unnecessary. And doctors may not always take the time, or have the time, to explain to parents what will and won't work in their child's particular case. For example, allergies are usually a problem for older children with asthma, while kids 5 and younger more frequently have trouble with viral repiratory infections. So make sure you understand what the cause of your child's asthma really is.
Answer: Closing the windows to keep pollen out of the house.

Article: When it comes to movies, we usually think of big actors, big budgets, big screens, and, if lucky, big profits. Unfortunately, that puts up some big barriers for aspiring young filmmakers and their dreams. However, thanks to easy access to technology, that's all changing. All one really needs nowadays is a camera, a computer, an Internet connection, and, of course, a good idea. With that, you can enter the microfilm world. Shooting a movie using friends and family as the cast has become a common class project for high school students. After a little editing on a laptop, some even decide their creation is worth sharing online. Microfilms are shot within a short period of time and last only a few minutes or even shorter. Most are completed on an extremely small budget and offer a cheap way for grassroots directors to realize their dreams. With a range of film festivals, they have taken off due to being perfectly suited to new media platforms such as mobile phones and notebook computers. They are also easily shared across social networks and microblogs. But microfilms are far different from the shorts commonly found on YouTube. A microfilm must have a solid and thoughtful plot. Most importantly, the movies are easily distributed and there can be no concern about long-term box office profits. Most people who upload a microfilm simply see it as an easy way to share their fun with a few friends and family. Others may be curious about what sort of reaction their production may receive from the general public.
Answer: Small costs for microfilms.
