It is all around you and everyday you come into contact with this supposed "monster" that can make your life completely miserable. Walk into any grocery store, pharmacy or major discount retailer and you will see loads of anti bacterial products that have been marketed to combat the effects that bacterium has on everyone's lives. What is this mysterious thing that drives people crazy? It is nothing less than the tiny, microscopic bacteria that surround us every day.

There are more than enough bacterial infections to go around. Most people experience at least one infection or bacterial disease in their lifetime. They are by no means any fun, and can actually be life threatening in some cases. It is important to know how a bacterial infection can harm you and what bodily systems can be affected. It may mean the difference between a healthy, happy life and one filled with pain, or even death.

We have all heard someone say at one point or another that they have pulled a muscle, but do any of us really understand what a pulled muscle is? A pulled muscle is a very common sports injury that occurs when the muscle fiber has been over stretched and begins to tear. Sometimes bleeding will occur from the tears and a bruise will form over the sore area.

One of the most difficult things for athletes to do, especially in extreme weather conditions, is to regulate their body temperature. On a hot day the body generates heat during exercise at faster rate than the atmosphere will allow it to dissipate. In extreme circumstances, even the atmosphere can make the body temperature rise, let alone allow it to dissipate heat itself.

While it can seem rather trivial, a jammed finger can be a very painful injury. Because our fingers need to be sensitive to touch and to have a lot of dexterity, they have a huge amount of nerve endings. This large bunching of nerve endings means that an injury can be quite painful.

We have all seen athletes in the Olympics or major marathons stumbling stiffly across the finish line, bent over and grimacing in pain. The problem is not a serious injury or fatigue, the problem is that their bodies have run out of the fuel they need to keep going. They have literally exhausted their resources and the body no longer has any fuel left in reserve. The muscles begin to tighten and cramp as the body begins to shut down from all the hard work it has been forced to do.
