“Estimating the price” of a human life sounds insensitive, although necessary in certain circumstances such as agreeing on a personal injury settlement, a decision in a murder case, or when sex trafficking organizations raise awareness for their cause. Humans are unique beings with unique perceptions and beliefs. We value individual humans within our life different amounts.
To me, a hero is someone who shows courageous strength, even when the future is uncertain. A person who values the impact they leave on the individuals they serve. A hero is a person who, regardless of their fears or the doubt in their success, shows up anyway. An individual that continuously exhibits mental grit is a hero. Heroes are all around us.
