Found this at FitnessGeared, good post about 30 or so common misconceptions (originally printed in Muscle Media I believe) about bodybuilding and healthy lifestyles, optimal nutrition etc. Makes for interesting reading and there are some interesting points in there, but is very long so be warned. Due to the variety of topics covered, I thought it fit best in off topic seciton.
