Agreed with both of the answers above, but you have to remember it is a very aggressive and constant sport. With any sport you play it make take awhile to adjust to the rules and ways of play. For instance a person going out on the pitch for the first time may be susceptible or pron to more injuries rather than a man that has been playing for awhile. There are strict rules that permit someone from tackling harshly. For instance you cannot clothesline or pick someone up and slam them into the ground, I mean you can do anything you wan't technically but you will be penalized for it. As being compared to other sports it involves more contact with continuous play, but if you learn how to play it's truly a sport that grows on you
