I'm pretty straight-laced and conservative compared to most in this field. When I was at school, it's true that the majority met the description you wrote... when I entered the job field, though, I found that it was quite the opposite. I think out of all the people I've worked with, interviewed with, etc, only one person has met the "weird" description you provided. The majority seem to be fairly "normal" in comparison.

Don't know if that means anything or not.
