Some might say having a hero at all leads to apotheosis and cults of personality; it could be dangerous. Also, if you ask someone who their hero is and they have an answer at all, usually it's someone who isn't living because posthumously their reputation can be changed more easily to allow hero worship. So, I'd say having a living hero is pretty rare. That said, do you have one?
I've thought about this and come to the conclusion that I do have a living hero and it's Anthony Bourdain. I've read his books, I've watched his TV show, and I admire him in such a way that I think he's my hero. If anyone's unfamiliar, he is a chef/author/TV personality who has done the things I want to do, been to places I want to go, comes up with the same observations and conclusions that I'd like to come to. I find myself in various situations thinking, "What Would Anthony Bourdain Do?"
It may sound a little ridiculous, but it's true. Do any of you have an living heros? If so, who and why?
