Unlike nose picking, pimple popping is a widespread habit that does come with its share of risks. For one, you leave yourself vulnerable to scarring when you pop pimples on your face, which is just unsightly. Secondly, and more seriously, you expose yourself to the risk of a bacterial infection.

Our fingers, perhaps more so than any other body part, come in contact with a vast array of bacteria every single day as we touch everything from the counters at Starbucks to the subway stair rails. And when we poke around in our skin, especially engaging in an activity like pimple popping that involves breaking the skin, we are introducing foreign bacteria into a wound, giving it a perfect environment to grow and thrive.

With an ever-increasing prevalence of methicillin-resistant Staphylococcus aureus (MRSA) infections, problems that result from zapping those zits may end up requiring a hospitalization or other drastic measures.

Hungry? Give It a Rest... Room

There are many, varied reasons why people have admitted to setting up shop for lunch (or another meal) in the bathroom - ranging from hiding the food that we’re eating to social anxiety that keeps us from being comfortable eating at a table with others. And it’s not just a few outcasts who are eating in the lav.

According to a 2014 study by SCA, a Swedish hygiene company, more than 8 percent of the more than 1,000 American survey participants admit to eating in the restroom.

In addition to the lack of suitable surfaces for placing food and the fact that the bathroom is one of the most germ-infested rooms in the house (then again, so is the kitchen, and that is where our food is prepared, presumably), the study also revealed that ten percent of Americans only “sometimes” wash hands after using the restroom, while one percent say they never do.
