EVERY DAY HEROES
Jonas Salk is an every day hero because he invented medicines for the disease of "polio" in 1955. More than 3,000 people died . Amongst these patients , US President Franklin Delano Roosevelt was disease. He saved much people.
He worked as a scientist. A typical working day for a scientis means starting work at 9 AM and finishig at 8 PM. A scientist work in a lab.
I would hate to be a scientist because you have to study very much. I would prefer to be a nurse is easier than scientist
