I want to see how many answers I can get.. help?

I am doing a PSA [public service announcement] in health. I have to pick a topic of something that I would like to talk about to my school and try and fix it. I chose fighting. I'm totaly procrastinating right now because it was due today but I was sick yesterday and today and haven't really gotten started on it.. I've thought of some reasons why fighting is troublesome at schools and how they can affect the students and stuff, but only 3 reasons :p so, if you would just look up for me 1 reason that would be much much much appreciated :]]]
