Over the years, many guests have made a lasting impression on Dr. Oz, but he says one man stood out from the rest.
In October 2007, Dr. Oz met Randy Pausch, a father of three and college professor who was dying from pancreatic cancer. Dr. Oz says people like Randy are the reason he went into medicine.
"I loved Randy Pausch. He was a hero to me," Dr Oz says. "When you talk to people who are dying, they tell the truth. There's no reason for them not to."
