Backpacks are available in all shapes and sizes. Most contain multiple storage spaces for books, notebooks, pens, cell phones, or water bottles. Compared to a shoulder-style bag, the backpack provides the best choice for carrying materials between school and home. Why? Because the body's strongest muscles - the back and abs - support the weight evenly. However, if the backpack isn't worn correctly, the weight of the pack causes additional strain to the body.
Asthma and allergies are big problems for many people in the U.S. With air quality becoming and issue in most of the major cities, folks sensitive to allergy or asthma triggers are at greater risk.

Allergen Immunotherapy has been available for some time to help alleviate symptoms in people with severe allergic rhinitis. This type of therapy can therefore reduce the person's need for medication to control symptoms and may be able to potentially cure a patient of their allergic disorder. While traditional allergen immunotherapy by injection can be effective at reducing patient symptoms in the long-term, a carry-over effect of new tablet-based vaccines, such as Grazax, has not been reported until recently.
