Bob Narev wasn't really frightened during more than two years he spent in a Nazi concentration camp, starting when he was 6.
Mr Narev, a German Jew, was taken to Theresienstadt concentration camp in Czechoslovakia in 1942, along with his parents and two grandmothers. Of the five, only himself and his mother survived.
"I wasn't frightened, but had I known what my mother had known, I would have been," the 80-year-old said.
Theresienstadt was a kind of holding camp, he said, and nearly everyone who went there was eventually taken to Auschwitz.
"When you are in that situation as a child, your memory turns off," Mr Narev said.
