The essay discusses different types of heroes, including police officers, firefighters, doctors, and lifeguards. Police officers are described as heroes for saving lives every day, from minor traffic violations to life-threatening emergencies. Firefighters have a long history of saving people from fires and deserve recognition. Doctors work to save lives and provide medical care. Lifeguards also risk their own safety to rescue people in dangerous water conditions and watch over large areas. The essay argues that while sometimes overlooked, lifeguards are heroes on the same level as other professions.
