Well, let's hope you never have to. I didn't think I'd have a situation like that, either.

That experience itself is similar to the hyperfocus state of ADD/ADHD - can anyone corroborate? I have had that diagnosis, then had it revoked. I have my own self-theories, including having low WM (which is why I recall that study), but I should really go try something like http://www.cambridgebrainsciences.com/

May I ask what you plan on studying? School was extremely easy for me once, and then extremely difficult (to complete).
