What Are Boogers? How They Form and Why You Should Occasionally Eat Them
Whether it's allergy season or not, warm or frigid outside and regardless of your age, boogers can clog up your nose and impede your breathing. There are many ways of removing boogers from your nose, whether it's blowing them out into a tissue, launching that "bat in the cave" snot rocket style or taking a more hands on approach by digging in there with your finger.

In the same vein as natural childbirth being healthier due to the mother/child transfer of microbes, boogers may actually boost your immune system due to "hygiene hypothesis." Scott Napper, a biochemist from the University of Saskatchewan in Canada, theorizes that eating mucus-soaked boogers can help introduce beneficial pathogens to kids, thereby warding off allergies, asthma and other autoimmune diseases that manifest due to a lack of pathogens.
With that said, whether you want to consume boogers is your prerogative. Just try to keep your nose booger free, lest you get a whiff of pepper and then...
