Breathing is something that is vital to life. It is something we all do and need to do constantly to enable us to live. If you are not doing it now then I m sorry but you cannot continue to read this, as you are dead. This article is not about breathing though; it is about what we breathe. Yep, but let us, for a minute, think about what may be in the air we breathe. Apart from the components of air such as oxygen, which is the bit we need, the air you breathe is full of other particles and you need to think about an air purifier to filter these potentially harmful particles out of the air or in other words purify the air. I am sure you have seen sunlight coming through you windows and when you are at a certain angle you have seen dust particles floating in the air. You breathe these in unless you can use an air purifier to remove them or hopefully most of them. Its not only dust though, people and animals drop flakes of dead skin which is why you need an air purifier. Tobacco smoke produces particles of smoke, which is why you need an air purifier, and vehicles also produce particles of smoke from their engines, which is why you need an air...

Flu season is just around the corner once again. But this time, it may be coming disguised as a serial killer. There is deep concern that a new killer flu, nicknamed Bird Flu, may mix with ordinary flu and kill millions of people. Jude Children s Research Hospital in Memphis characterizes this killer flu -- and take note that Dr. Webster has been studying influenza for the past 40 years: This virus right from scratch is probably the worst influenza virus, in terms of being highly pathogenic, that I ve ever seen or worked with. Public health experts, including those at the World Health Organization, fear a catastrophe. In preparation, the United States has ordered 2.3 million doses of an antiviral called Tamiflu. has decided to place all of its chips on an experimental vaccine, a vaccine that is based on an early seed of bird flu, which most experts agree has already mutated into something quite different, and that means when bird flu gets here, it may not respond to any vaccine. The most astonishing fact about this new bird flu virus is how much science doesn t know about it. The mystery remains of how people get infected. Is it by breathing the...

Stock exhaust systems are designed simply to provide a conduit for spent gases to move from your engine to your tailpipe - no more, no less. On the other hand, performance exhaust systems are engineered to maximize your engine s exhaust flow, giving you: - Serious horsepower and torque gains - Distinctive, growling exhaust tone - Improved fuel economy Horsepower and torque In case you skipped out on Auto Shop back in high school, I am here to give you a quick lesson on the mysterious inner-workings of your engine s cylinders. Without cylinders, your vehicle could not drive around, unless you could convince your friends to lend you their backs and push you all over town. That s because the majority of your horsepower is generated right there in your cylinders through a fairly straightforward process, called combustion. First, the cylinder sucks a mixture of oxygen and fuel gasoline or diesel into its chamber, where it is then ignited by a spark plug or glow stick. These three ingredients create a controlled explosion, or combustion, which generates both energy and waste gases. That energy transforms into wheel-turning torque to propel you down the...
