It's probably one of the worst habits you can have - picking your nose and eating it - but it turns out the gross act could actually help you ahead of flu season.
A study from the American Society for Microbiology found our beautiful boogers can strengthen our immune system and even protect teeth from cavity-causing bacteria.
Researchers are now looking at ways to create 'synthetic nose boogers' so they can be turned into a cavity-fighting chewing gum or toothpaste.
Scientists also say people who pick their nose and eat it are usually happier and more in harmony with their body.
