Am I autistic?

I've always thought of myself as having autistic tendencies. Here's why:
- I have no trouble concentrating amidst a crowd. In fact, i almost always prefer to focus intensely on one thing at a time,
- I have a very vivid imagination, thus my ability to concoct storylines ranging from the soberly dramatic to the outrageously insane,
- I'm good with remembering numbers, like telephone digits or people's birthdays. I'm also good with patterns and logic.
- I talk to myself. A lot. Most of the times not consciously,
- I often find myself rather awkward in social situations as I refuse to go out my way to entertain others.

Today, following up a related topic that vera brought to the lunch table, i began to self-diagnose and reached an autism quotient (AQ) of 23. That's about an average math contestant, whereas scorers of 34 or above probably have Asperger's.

So, i guess i'm just another anti-social face in the crowd.
