Wait so you're letting something that happened 10 years ago ruin your quality of life? What are you, America?
I should also acknowledge that there are sports which have a lot of dangerous contact, but where the contact is not of the essence - i.e. does not contribute to the win, but may even lead rather to a penalty if not controlled appropriately - games like Rugby football or American football, for instance. These I dislike for that element but do not condemn.
