“Innsbruck-based lung specialist Prof Dr Friedrich Bischinger said people who pick their noses with their fingers were healthy, happier and probably better in tune with their bodies.

He says society should adopt a new approach to nose-picking and encourage children to take it up.

Dr Bischinger said: ‘With the finger you can get to places you just can’t reach with a handkerchief, keeping your nose far cleaner.

‘And eating the dry remains of what you pull out is a great way of strengthening the body’s immune system.

‘Medically it makes great sense and is a perfectly natural thing to do. In terms of the immune system the nose is a filter in which a great deal of bacteria are collected, and when this mixture arrives in the intestines it works just like a medicine.

‘Modern medicine is constantly trying to do the same thing through far more complicated methods, people who pick their nose and eat it get a natural boost to their immune system for free.'” —Ananova [via dangerousmeta]

Can the revulsion that this image causes most people be explained entirely in terms of their socialized manners? Given the evidence that the emotion of disgust serves an important evolutionary purpose (BBC), could there be an evolved disincentive to picking one’s nose, in contrast the the advantages touted here??
