i play football(american) so i have a few stories about injuries. I have been tackled by and eight grader(when i was a 6th grader) who had 100 lbs more than me and i ended up skidding across a baseball field(our practice field duobled as a playground). I have been dogpiled on, speared, and otherwise magled during games. I have nearly broken my arm when someone kicked it and it bent the wrong way and i have been pucked and cleated(them scraping their cleats into my shins ect) and have been punched and kicked a few times. Even through all this its still worth it. Sports are great. but it helps to keep an eye out for any heavy flying objects,ie. shot puts,discusus, javilins9that would REALY hurt)ect.
