My Grandfather worked in an abitoir for more than 40 years and has 4 fingers and 1 thumb missing from the knuckle to show for it. When I was younger he would tell us that he lost his fingers by picking his nose, one day they had got stuck and just come off!
I never really believed him, after all how could someone with an average sized nose have 4 fingers and a thumb stuck up there! However, it didnt stop me from suggesting to my son who had started sticking his fingers up his nose to ask Grandpoppy how he lost his fingers :P
A childhood belief about picking my nose

- I thought your fingers would grow back if they got cut off— Nate
- i used to think that biting my nails would make my fingers fall off! ;)— Cassandra
- i used to believe that polishing your nails also consisted of painting your fingers. Anon
- When I was a kid, I slept with my fists balled up because I thought if I didn't, E.T. would eat my fingers. — Brian
