Picking one's nose and eating it might be healthy

Mucophagy (literally mucus-eating, also referred as picking one's nose and eating it) is the consumption of the nasal mucus, boogers, and other detritus obtained from nose-picking.

Some research suggests that mucophagy may be a natural and even healthy activity, which exposes the digestive system to bacteria accumulated in the mucus, thereby helping to strengthen the immune system.
