Why is licking your fingers to separate papers while counting them a bad habit and a health risk?

Answer 1

Many people develop a habit of touching one or two fingers to their tongue to wet them while counting paper items (paper money; checks; school papers; receipts, etc.). Banker tellers stopped this habit long ago; they now use a special sponge that is kept moist inside a special container.

The primary health risk is that saliva contains millions of germs. These germs transfer to both objects and paper. Second, people do not wash their hands in between tongue-touches, so anything that is on the papers or currency is being transferred to the person's tongue.

Overall, it is a disgusting habit. Observers cringe and prefer not to touch what has been contaminated with someone's saliva.

Answer 2

Licking your fingers introduces germs from your mouth onto the papers, increasing the risk of spreading bacteria or viruses to yourself or others. This habit can also transfer chemicals or toxins from your fingers onto the papers, which can be harmful if ingested. Additionally, constant moisture from licking can weaken the paper or cause it to break down, making it more challenging to handle.
