The word hero is thrown around so much nowadays, whether for some 17 year old sports hero, or someone who does something vaugly interesting for fun/charity/whatever.
however, after the US shooting, I read this, and this guy truely deserves the title 'hero'.

"Israel Professor Liviu Librescu, 75, blocked the doorway of a classroom from the approaching gunman, his son has said.
Students have sent e-mails to the mathematics lecturer's wife Marlena, telling of how he saved their lives.
Son Joe Librescu, in Tel Aviv, said: "My father blocked the doorway with his body and asked the students to flee. Students started opening windows and jumping out.""
It sounds like he didnt make it out alive, but he was one brave man .
