Italian Scientist, turning 100, still works

Rita Levi Montalcini, a Nobel Prize-winning scientist, said Saturday that even though she is about to turn 100, her mind is sharper than it was she when she was 20.

"Above all, don't fear difficult moments," she said. "The best comes from them."

"I should thank Mussolini for having declared me to be of an inferior race. This led me to the joy of working, not any more unfortunately, in university institutes but in a bedroom," the scientist said.
