The story lines are fake, like a soap opera, but the moves and action are real. If you ask most wrestlers, you will be surprised at the potentially life threatening injuries that they suffer. Rey Mesterio is on the shelf again for another injury. He has had 5 surgeries on one Knee. Triple H has had a couple of career ending injuries. However, his work ethic, determination and heart helped him bounce back when the average competitor wouldn't. Stone Cold and Chris Benoit both broke their necks. Brett Hart suffered multiple concussions that helpd cause him to retire.
Rememeber their name answers your question, World Wrestling Entertainment. It's athletes entertaining you.
