One of the worst things you can do. If you have a 5x magnified mirror, look in it when you pull the nose hair out. You will draw blood. That can get infected and it "can" reach your brain and kill you. The nose is nothing to mess around with.
Mistercitizen will probably live to tell the tale of his nose-hair yanking adventures
I strongly doubt anyone is going to die from a drop of blood you need a magnifying glass to see
Kind regards from another yanker.
