Considering himself a lucky man, Dr. Zuckerman says people who struggle against the odds inspire him.

Question: Who are your heroes?

Joseph Zuckerman: The real heroes in life are to me, people who have problems, have medical problems, have personal problems that have to persevere against significant odds. When I get up early in the morning and go to work, I'm happy to go to work I have not had to deal with those things, but I see it in a lot of my patients, I see it in a lot of people in the hospital, you know, patients in the hospital. It is very challenging for them to do that. People that can persevere in a situation that makes life difficult, even tragic, all right, those are my heroes.
