Peter's right, you might find out something interesting about yourself.
I don't know much about hyperlexia except for what is on wikipedia and it would be hard to diagnose in an adult, I think, without knowing the childhood history.
I know you're right. I should try and get properly checked out and try and find out for sure what my problems are, but I have a major doctor phobia at the moment. I haven't been to a doctor in years and if I were to register with one I know I would have to go through all the check-ups and I don't think I want that at the moment.
I'm not really all that worried about the problems I have. I have a great life. I'm really just curious, although not enough to deal with a doctor.
