There are definitely things we don't touch like slugs and live electrical wires, anything in a public restroom, but this research may make you want to wash your hands repeatedly.

A number of surfaces In New York City were tested to see which had the most bacteria on them.  The filthiest:

  1.  A McDonald's door handle
  2. Cash/coins
  3. A park bench
  4. Parking meters
  5. Credit cards
  6. Public bathrooms

According to research from Mastercard and the University of Oxford, the average bank note is home to 26,000 types of bacteria including E. Coli. And the average coin has more germs than on a toilet seat! It’s perhaps not surprising given the number of people that exchange money on any given day, many of whom do not wash their hands before or after handling it.

I wash my hands every time I come in from traveling, and whenever I handle cash and coin. It is advisable that you get in the habit too, and remember soap and water is better than sanitizer.  With all those things out there that we don't want to touch, Its the only way I feel comfortable because of course, it is illegal to launder money...LOL
