Julia was interviewed on the radio about her article on modern-day heroes. She argues that everyday people like parents, teachers, police officers and firefighters are true heroes because they sacrifice their own needs and interests to help others. Julia defines a hero as someone who puts other people's well-being and safety above their own desires. While professionals take risks to save lives, ordinary people also act heroically when they intervene to help someone in danger, even at the risk of their own safety.
