Reportedly the genes for intelligence and schizophrenia are linked: http://www.schizophrenia.com/sznews/archives/003341.html

No clue. I know a lot of smart people who aren't crazy though.

I think with Courtney (who I have a mutual friend with), she's been isolated just enough to let the crazy foster and the smarts carry her through.

I admire her, not without caveats.

I've often wondered if famous people tend to go off the deep end more than the rest of us because they're constantly surrounded by people who tell the what they want to hear.
