| I've taken many objects to my face throughout my life, and although they probably lowered my IQ tremendously, they NEVER gave me a nosebleed. The major ones I remember at the moment include basketballs, tetherballs, baseballs, softballs (which are NOT soft at all -_-), lamps, doors, and a rock. And not one nosebleed. I got my first nosebleed two days ago. I had an itch so rubbed my nose from the outside and I felt something trickling down inside. What the heck! It was like menstruating from my face, and all I did was rub my nose a little. o_o
A major up-side to having that nosebleed was having the clearest sinuses ever afterwards.  It makes me actually look forward to having another nosebleed. | 
My first nosebleed!
