Hero is a word that is often overused. I know this because I work in the news business. We are quick to call people a "hero" because, well, it sounds good. It might make you want to see what's so heroic about the person featured in a story. But it's hard to deliver when you give someone that "hero" title. I mean, a true hero will tell you he/she is not a hero. That guy who says he's a hero - he's not.
That said, I'd like you to take some time to read about a TRUE hero. An Army Ranger from Minnesota saved six of his fellow soldiers during battle in Afghanistan. He lost his life in that fight. But (and here's where he goes extreme hero) he wasn't done giving. He donated his organs and tissue to help 75 strangers.
Here's a link to the story. Think about Cpl. Ben Kopp the next time you call someone a hero.
