Agree with many things covered in this thread:
1) VX owners like attention (admit it)
2) Are all ages, shapes, origins, etc.
3) Obsessive or compulsive (you probably do pay less attention to you spouse/other)
4) Active but not necessarily outdoorsmen (I don't like to sleep there either)

I would add "too much time on our hands" or insomniac or easily bored...or perhaps slightly insecure. Marlin could possibly add potentially paranoid since he takes showers and thinks about FBI profiles of him and his buddies (then of course I log on and comment about HIS delusions - that's probably worse).
