A week ago, James and I lost a very dear friend to an incurable brain tumor. His name was Tony Milin, and he was in James's class at Wash U. Tony was a sweet, fun, kind, happy guy, and we spent hours on end hanging out with him and talking. I know that for the rest of his life, James will never operate on a patient with a brain tumor without remembering his oldest friend from medical school. We'll miss you, Tony...
