Yea Nothing is fake. Its choreographed, but nothing is fake. Its still a toll on your body. The way it works is that the writers/owners write up scripts, just like in a soap opera. Usually is a wrestler isnt getting any reaction, he is written off, or changed characters or what not. Some have great charisma, and therefore are sort of shoe ins to be pushed to the top. The Rock for instance. Its not complicated. Oh yea, and I used to be a huge mark, till about 2-3 years ago.
