Do you see the world in terms of your job?

As I get older, (I turn 30 this year), I notice more and more that I'm view the world in terms of my job.
It's worrying because I know both my Dad and Grandad used to do this. They were builders/roofers and I could guarantee that if we were watching a movie then within 30 seconds of an explosion I'd here a comment along the lines of:
"That's gonna cost a fortune to rebuild" or "they won't be able to fix that, they're gonna have to knock it down and start again."
It always used to annoy me as a child so I always promised myself I wouldn't do this but last night I found myself doing the exact same thing.
