A man picking his nose
Nose-picking is the act of extracting dried nasal mucus or foreign bodies from the nose with a finger. Despite being a very common habit, it is a mildly taboo activity in most[ambiguous] cultures, and the observation of the activity in another person may provoke mixed feelings of disgust and amusement.[where?] The Greek name for nose-picking, rhinotillexis, is sometimes used in medical literature.
Nose-picking is an extremely common habit, with some surveys indicating that it is almost universal, with people picking their nose an average of about four times a day. A 1995 study into nose picking, requesting information from 1,000 randomly selected adults, gathered 254 respondents. It defined nose-picking as "the insertion of a finger (or other object) into the nose with the intention of removing dried nasal secretions". Of those who responded, 91% said they were current nose pickers (but only 75% of these believed everyone did it) and two people claimed to spend between fifteen to thirty minutes and one to two hours a day picking their noses.
Mucous membranes in the nasal cavity constantly produce a wet mucus that removes dust and pathogens from the air flowing through the cavity. For the most part, the cilia that also line the cavity work to move the mucus toward the throat where it can be swallowed. However, not all the mucus stays fluid enough to be moved by the cilia. The closer the mucus is to the nostril opening, the more moisture it loses to the outside air, and the more likely it is to dry out and become stuck. Once dried, the mucus typically causes a sensation of irritation that leads to the compulsion to dislodge the itch by picking. Other reasons to remove excess dried mucus include impaired breathing through the nose or a concern that it may be visible to others in the nostril openings.
In many cultures[which?] nose-picking is considered a private act akin to defecation, urination, flatulence, and belching. Mucophagy, the act of eating the extracted mucus, may be considered more taboo, and is sometimes portrayed in comedies. To be caught nose-picking may be considered humiliating.
Medical risks 
Risks may include an increase in the diversity of nose flora, or occasional nosebleeds. One case of rhinotillexomania resulted in perforation of the nasal septum and self-induced ethmoidectomy. Nose picking, however, should not affect the sense of smell, as the nasal cavity where the olfactory nerves are located is too high up to reach.
Cultural references 
A popular saying in many English-speaking countries is, "You can pick your friends, and you can pick your nose, but you can't pick your friend's nose." The 1968 Mothers of Invention song "Let's Make The Water Turn Black" tells a true story of an adolescent acquaintance of composer Frank Zappa who habitually saved his own extracted mucus on the pane of his bedroom window. An episode of Seinfeld entitled "The Pick" deals with the social stigma of publicly picking one's nose. Harry, a character in Requiem for a Dream mentions enjoying picking his nose in the first chapter of the book.
