A lot of them don't seem to apply to me. So, here's a few more... :) You carry on conversations in your head with imaginary people, and complain bitterly to your friends about how the imaginary characters always seem to win. Instead of weightlifting, your workout schedule includes a visit to the local library. You read out of date text books because you are curious about what people used to think was true. (For fantasy/sf writers) You know more about the workings of your imaginary countries than you do about the one you actually live in. (For historical writers) You despise fashion in general, but you know what points are and why they need tying, and can explain all the major fashion trends for one or more specific 100 year period spans. You have a folding keyboard and fully functional wordprocessor for your PDA Any more?
