I get 4 hair and beard cuts a year and each time there is about 1/8 of a pillow case worth of hair on the floor. So it would take me 2 years to stuff a pillow case and since I've had 60 years of hair cuts it would mean I could of stuffed 30 pillow cases. (I just got my Christmas hair cut so thats what got me thinking about this question). Cheers!
