I just think common sense should prevail. If I'm asking about a good chest routine, I don't think age or body fat would matter. If I'm asking about how much creatine to take, none of that stuff matters.
I'm not a big fan of tracking body fat (maybe 'cause mine is, like, 80%..lol). I prefer looking in the mirror.
Granted, a lot of posts here need a lot of the info posted above, but not necessarily all. I think it should be common sense what to divulge when asking quetions, though when in doubt, don't leave it out...
