The Science of Nose-Picking:-Most everybody does it whether they admit it or not, both in kids and adults. In fact, according to one research survey, people do it about 4 times a day. In 7.6%, they do it >20 times a day! Nose-picking, also known as rhinotillexomania in medical-speak, generally is a benign, sedentary (and private) solo activity, but when excessive, can lead to a number of medical problems including nosebleeds (25% of nose-pickers), septal perforation, staph infections, etc. In one extreme case, it even led to a self-inflicted ethmoidectomy (sinus surgery)!!!!!!!!
