Dude

Scientists at a number of universities including Harvard and Massachusetts Institute of Technology (MIT) say parents should not discourage their children from picking their noses because they contain ‘a rich reservoir of good bacteria.’

Eating snot can also prevent bacteria from sticking to teeth, according to the article published in the journal of the American Society for Microbiology.

The findings even suggest snot could defend against respiratory infections, stomach ulcers and even HIV.
