That's funny. We actually have the pre-eminent neurosurgeon in the world here in L.A. His name is Keith Black, (same as the famous engine builder from days of yore). He's African-American, extremely famous in the medical world. (Cover of Time magazine, etc.). He has removed life-threatening brain tumors from two people I know personally and they are both 110% fine.
(Went off on a tangent there but hey, it's OT).
