I am sure most here are the same, but there is a "lifestyle" associated with lifting seriously that also spills over into how you all eat and act in public. I doubt I discuss lifting with my on and off training partner outside of the gym...but you can bet if we go out, how we eat or even what we do may just be affected in some small degree.
Hell, even in the gym we aren't talking about lifting much outside of what we are actually doing.
As far as living this, it nefer has been about talking about it all day long. It is about doing it all day long and those with similar interests get in where they fit in.
Either way, why shoot down the guy who is really excited as a newb?
