Eating bogies is good for teeth and overall health, scientists conclude*
Austrian lung specialist Professor Friedrich Bischinger, who also contributed to the study, said research show people who pick their noses are healthy, happier and probably better in tune with their bodies.
"Eating the dry remains of what you pull out is a great way of strengthening the body's immune system," he said.
"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."
