soccer vs kick-boxing

After having a three years break I'm thinking of turning back to martial arts. My reasong for quiting kick boxing was the coming high school exams, so i had to quit otherwise i could broke my arm or fingers just before the exam and couldn't get in a dent high school. After the exams i found other sport activities such as rowing but my best loved sport was always the one i had to quit. Nothing like puching and kicking some sand bag to give out your stress. On the other hand it is healthy (if you don't get beaten up so badly in training) and you become more flexible when you are triyng to kick higher. At the end I also want to say that kick boxing is a less violent sport than soccer (at least in turkey) for the ones who think martial arts are unnecessary and violent.
