Everyday, human beings unknowingly come into contact with objects covered in thousands of dangerous germs. In order to stay sanitary and know what you’re touching before you touch it, read and consider the list below:

Money: Think for a moment about the number of hands the money you’ve touched today must have passed through before reaching yours. You may have showered thoroughly this morning, but the homeless man who used the same dollar bills to buy booze the other day probably did not. The money you handle not only holds value–it carries a ton of bacteria, and as a result is often dirtier than toilet seats.

Light switches: Nobody thinks to wash their hands after turning on the lights, but we ought to. The average light switch in a public area holds about 217 bacteria per square inch, and that amalgamation of germs from the public’s fingers are instantly transmitted to yours in the split second you flip that switch.

Keyboards: Studies show that one out of four publicly used keyboards are dirty enough to pose a threat to your health. The best way to keep all the crevices in a keyboard clean is with a can of compressed air, cloth, and detergent.

Cell phones: The cell phone is not only a popular piece of technology—it is also one of the most convenient ways thousands of germs can easily make their way to you. The heat that cell phones produce creates bacteria, which we transmit from our hands to our faces every time we make or answer a phone call (which happens, for most of us, a few times a day or more). Consider using an anti-bacterial wipe on your cell phone every once in a while.

Toilets: This one should be a given. The cold surface of a toilet seat hosts about 295 bacteria per square inch.

Shopping carts: This is another situation where the fact that thousands of dirty hands are indirectly coming into contact with yours just seems to slip your mind. A University of Arizona study shows that shopping carts are covered with more bacteria and viagra online pharmacy fecal matter than public bathroom surfaces. Wipe the handle first, then shop.

In addition to the techniques mentioned in this article, air purifiers are important for avoiding germs in the air. Curbside Air Purifier products or the Austin Air Purifier are good options to invest in that keep

the air you breathe sanitary.
