“Studies have found 32 different bacteria and 28 different fungi underneath fingernails.”

And it doesn’t matter if your nails are natural or false because there is an increased probability of carrying microorganisms, which makes it hard to clean with handwashing or scrubbing.

Kaplan further warned that the bacteria can be transferred to your system ‘by scratching, nail-biting, nose-picking and finger-sucking’ and can go on to cause an infection.

In addition to explaining why we should cut our nails, there’s a little known fact about clippers themselves that’s still leaving people scratching their heads to this day — that mystery being the small hole on clippers.

Many (myself included) have long ignored this design feature, presuming that it’s not really for anything, yet it turns out that the hole is there so that the clippers can be connected to things like keychains, toiletry kits, and so on.

A post on Facebook has gone viral of late sharing one man’s story about how he came to learn about the purpose of the hole.

The post reads: “My mother-in-law couldn’t stop laughing when she realized I had no idea what the tiny hole in a nail clipper is for. Now I wonder… am I the only one who never knew?
