Did you know that plucking or trimming NOSE HAIR can be dangerous. 

"There’s an area on your face that the medical community has ominously named “the triangle of death.” The top point of the triangle is the bridge of your nose with the bottom of the triangle being above your upper lip. This area of your face is obviously close to your brain which makes getting infections in the triangle more dangerous than getting a cut on your knee.
Not only is tweezing nose hairs incredible painful, it can leave the skin open from where you yanked the hair out. The hair in our nose is the first line of defense for filtering out the bad things we breathe in, so there’s plenty of germs trapped in there. The germs can then enter the body from the wound and cause an infection – staph, meningitis, etc. These scary bacteria can then infect the brain, leading to serious medical outcomes like paralysis or even death."

The bottom line is DON'T PLUCK IN THE TRIANGLE.  And don't pop pimples or pick your nose as either could leave your skin open to infection in vessels the feed the brain.  Not a good situation. 

To avoid the common cold and flu, you must keep your hands, forearms, elbows and anything else away from your face. This takes some discipline as we all tend to bring our hands to our nose, mouth and eyes to make sure we look good and/or to scratch an itch. If you bring anything or any part of your body to your face and any germs are transferred to your nose or eyes, those germs can get to the nasal mucous membranes and  to the nasopharynx (where the mouth and nose meet). Once they get there you have a good chance of getting sick.  Germs need a carrier to get to your nose, eyes or mouth and that carrier is usually your hands. Keep the hands away from your face and the chance of being infected with those germs is diminished.

It’s been said that if you drink from an infected person’s glass, you have less chance of getting sick than if you touch that glass and then rub your eyes or  nose.

Bottom line – DON’T TOUCH YOUR FACE  unless it’s with a sterile cloth or tissue. Try to just let any itch that you have on your face go away. It eventually will without your rubing it.  The next time you feel your hands going to your face – STOP.  You’ll be happy you stopped.
