Do NOT eat the snot - It may seem like a good idea, or perhaps a tasty treat. If you are alone, then if you truly decide to then go right ahead. However, keep in mind that snot is stuff your body blocked from coming into you. Never eat your snot in public, unless you have some sort of mental issue that can only be expressed with public snot eating.

I have found evidence contradictory to this here
