Scabies is an infestation of the skin with the Sarcoptes scabiei mite. It is characterized by intense itching , usually at night. Scabies is a relatively common problem caused when the scabies mite burrows into the skin of an unsuspecting individual. As the mite burrows, it lays eggs in the surface layer of the skin. Several days later the eggs hatch and the mites begin to move. Scabies is highly contagious through skin to skin contact. Although the mite doesn't live very long away from people, it can be contracted by sleeping in the bed of someone who has the problem. Intense itching is the most common symptom of scabies. This usually occurs at night. Unlike hair lice, it is essentially impossible to see the mite without the aid of a microscope. However, itching and scratching will often cause characteristic nodular bumps in areas infested with the scabies mite. These can occur anywhere on the body except the face.

It's true; insomniacs may have dirtier minds than people who get a normal amount of sleep. Before you start thinking that lack of sleep can distort your moral code, take heart. It is not your ethics or morals that are in danger, but your brain itself.

Waste that accumulates in the cells during the metabolic process is released from the cell into the fluid between each cell (the interstitial fluid). This is when the lymphatic systems kicks in. It sucks up this waste and fluid, incorporates it into the lymphatic fluid, filters it through the lymph nodes, and then it dumps it back into our circulatory systems.
Since its release in 1998, the breast cancer stamp has raised
over $50 million for breast cancer research. Perhaps one of the
reasons the breast cancer stamp has been such a success is that it
makes it so easy to do good: spend a few extra pennies on postage
for mail that has to be sent anyhow, and youve done your part
in supporting the cause.
The breast cancer stamp is the U.S. Postal Services first
semi-postal, a stamp that is sold above its actual
postage value. The stamp, which covers 37 cents worth of postage,
costs 45 cents. Those pennies have added up, with more than 650
million stamps sold so far. Beth Brophy spoke to Ethel Kessler, the
art director for the breast cancer stamp, who was diagnosed with
breast cancer in 1994.
Were seven years past the release of the
breast cancer stamp. Are you surprised by its popularity?
Im in shock and awe that we created something that
resonates this much with so many people. The stamp was supposed to
