My mind, or rather my nose, is blown:

'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.'
