When is the line crossed?

Greetings All,

    I found myself contemplating the other day, “When exactly do you become a bodybuilder?”  Is it technically when you start training like one?  Is it when that’s what everyone perceives you are?  Some scream you are not a true bodybuilder until you step out on stage in a competition.  I honestly don’t know.   

    The same could be said for the question, “When exactly do you become a nerd?”  Is it when you start talking fervently about Star Trek and Battlestar Galactica?  Is it when that’s what everyone perceives you are?  Some say that nerds are just born that way.

    I am told that perception is everything, but can one perception trump another?  If you are a nerd who gets into bodybuilding, do people forget the nerd perception all together?  Vin Diesel (action star extraordinaire) has the persona of big muscled tough-guy, but in real life he has very geeky passions (D&D, computer games, and I am told LARPing). 

    When is it that that line is crossed?  I am going to go with a combination of inward and outward perception.  You won’t be a bodybuilder until people around you see you as such, as well as you seeing yourself as such.  The same goes for being a nerd (not in a derogatory sense).  My problem is when have I successfully blended the two?
