When Les Held was 6 years old, he and his family were sent to a concentration camp. But each time the Nazis tried to kill him, he cheated death.

Despite going through those hardships as a little boy, Held went on to live a life filled with optimism and joy.

"My dad is amazing," Les' daughter Elizabeth Leibowitz told TODAY. "He's the most giving and caring person. He only want to help others."

"We decided he's here for a purpose in life... helping people taking care of his family," his wife Sandy Held said. "He's the happiest person I know!"
