try running as fast as you can while dribbling a ball and getting slide tackled from behind right onto your head. or challenging for a ball in the air and headbutting somebody. or (goalie) going up for a ball, catching it, and then getting your legs taken out from under you, and landing on your head. or (goalie again) diving into a heard of legs, kicking at the ball that you have in your hands, and taking a sharp blow to the back, which you still feel 2 years later. yup soccer is for pussies.
