First, who is a bodybuilder?  In my opinion, anyone who is taking part in an activity which preserves LBM (lean body mass) is a bodybuilder.  An eighty year old with a hip transplant who gets sent to physical therapy has just entered the world of body building.  Same for the sixteen year old who starts lifting weights to make the football team.  

Your body can only be in one of two states: anabolic state -  the building of LBM, or the catabolic state -  the breaking down of LBM.  So unless your ready to give in to the aging process, which is the breaking down of the body, body building is for you!

Make no mistake about it.
