Great question and topic. I know it is semantics but I truly believe we are surrounded by heroes. But I use the definition made famous by Romain Rolland "A Hero is a person who does what they can." or Maya Angelou "A hero is a person intent on making this a better place for all people". I think there are many people who do that every day. What I thought of when you asked the question is "legend". I think there are legends. Off the top of my head I'll take Malala Yousafzai. And of course Todd Beamer, Mark Bingham, Tom Burnett, and Jeremy Glick, who were the guys that killed the terrorists on flight 93 on 911. Then there all of the teachers and school staff who saved kids during school shootings. Plus there are all the young people around the world who are standing up to dictators. And the young people who risk their lives every day just to get educated.
