"Do not take money in a mouth! They such dirty, you after all do not know, who touched them!" Your mother spoke how also all mothers of all generations spoke before it. While you tried to save the money in savings deposits, buying shares, bonds, and thought out various methods of economy of money, your mother was excited most of all with preservation of your health.
But mums were not one. In the beginning of 20 centuries, Dr. Thomas Darlington, the commissioner of public health services of New York, presided over experiments on detection of bacteria on notes and coins. On February, 24th, 1905, New York "Times" has reported that the doctor has offered Darlington to Committee of the House of Representatives on banks and currency - "it would be desirable, in interests of public health care that the polluted bills to be withdrawn from circulation in the shortest terms".
In Japan, mums had real effect. There people can go to "a pure cash dispense" and receive yens which pass between rollers heat uped to 392 degrees, enough, to kill the majority of bacteria.
It goes without saying that bacteria are propagated everywhere in environment, and the majority of these microbes are harmless to the person. Whether microbes on money us can trouble? In 1972 in the American Medical Association research of bacteria on 200 coins and notes was conducted and harmful faecal bacteria golden staphylococcus for 13 percent of coins and 42 percent of notes have been found out. In research the conclusion has been drawn: "Money is rather dirty".
Other research was spent by University of California in San Francisco. Overseeing by 113 examples of "a real life" - money resources from an epicure, mails, news-stands, and other places of the general use where money passes from hand to hand was conducted. On the majority of token moneys there were harmless organisms, but 18 percent of coins and 7 percent of notes have been infected by colonies of an intestinal rod and potential pathogens staphylococcus.
Everything that falls you into hands can get on money. And hands are hardly sterile.
Speaking about hands and bacteria, dermatologist James Lejden asks a rhetorical question "Where bacteria are hidden?" In the late eighties, it has carried out the test in which closed damp spaces under nails of volunteers. "You will find there hundred thousand, even millions bacteria," he speaks. "Sometimes the quantity of bacteria under one nail is more than on other part of a hand." Each time when volunteers washed hands, the quantity of bacteria decreased, while in long run them almost does not remain.
In general, the skin resists in all methods to ectogenic bacteria. Its external bed forms an effective barrier, and a skin surface too dry or too sour for many microorganisms. In an oral cavity, a saliva - our natural mouth wash - contains antibody antibodies. Any microbe which is going to be introduced through a skin or a mouth should struggle with all immune system of an organism. To put it briefly, the human body does good enough work on protection itself.
So, what we can make with dirty money and microbes for currency? "The most widespread problem is absence of washing of hands. There are many bacterial diseases which propagate because people do not wash a hand after descend in a toilet".
George Marchin, the graduated in a military academy-professor of biology at University of the State of Kansas, speaks, hands as a rule, should come into contact to the person at distribution of virus diseases. "The virus gets on hands, and then you touch a nose or rub eyes. Wash hands as it is possible is more often.
Thus, the best method to protect is to wash hands, after use of money and especially after toilet visiting. Also it is all your mum spoke to you. Thanks you, mum.
