There are more than 48,000 species of mites. As far as we know, exactly two of those live on human faces. While their relatives mostly look like lozenges on spindly legs, face-mites are more like wall plugs, long cones with stubby legs at one end. They don’t look like much, and most of us have never looked at one at all. But these weird creatures are almost certainly the animals we spend the most time with.
They live in our hair follicles, buried head down, eating the oils we secrete, hooking up with each other near the surface, and occasionally crawling about the skin at night. They do this on my face. They probably do it on yours.
On August 1, 2007 the world’s largest rug was completed at the size of 60,546 square feet or 5,625 square meters. It took a whole year and a half to finish the rug with the help of 1,200 weavers working from three different villages. The weavers, from Iran, used thirty eight tons of wool and cotton which created two billion knots. This rug was made for a mosque that is now being constructed in the United Arab Emirates. About half of the money made (estimated at 5.8 million dollars) from the sale of this mammoth rug went to the villagers who wove it.
Humans lose between 30,000 and 40,000 skin cells every hour. During a 24-hour period, a person loses almost a million skin cells. The human body is made up of roughly 10 trillion cells in total, 1.6 trillion of which are skin cells.
Human skin is composed of several layers, and the outer layer is called the epidermis, which is composed of cells made of keratin called keratinocytes. Keratinocytes are formed in the lower level of the epidermis, which bonds with the second skin layer called the dermis. The new skin cells slowly push their way up to the top epidermal layer, where they die. The top layer is called the stratum corneum. Eventually, the dead cells break away from the epidermis and fall off, making room for newer cells to come up from below.
It takes approximately one month for new skin cells to make their way up to the top layer. This means that the skin a person had the month before is composed of completely different skin cells from the ones he has in the current month. The dust that collects on tables, shelves, window ledges and other areas of the home is made mostly from dead human skin cells.
The Pazyryk Persian Rug
Dating from the 4th century B.C. and at approximately 2400 years old, the Pazyryk rug is the oldest known Oriental rug. The rug was discovered during an archaeological excavation in 1949 in the Pazyryk Valley in the Altai Mountains of Siberia.
The exact location where the rug was found was a semi-frozen burial tomb. The Pazyryk burial tombs were building into the mountainside closes to the borders of Kazakhstan, Mongolia and China. The tombs were very durable. They were constructed of wood and boulders and their inner structures were extremely well-designed and well-constructed. All of these factors contributed to the preserving the rug so well through the centuries. Radio-carbon dating, which was done to determine the exact age of the rug placed it at about 2,400 – 2,500 years.
