Seriously man, I have never been there, despite living in a country famous for thirty of years of terrorism, despite years of riding motorcycles, despite years of flying, despite years of being a part time soldier. I have never seen much in the way of trauma. But I have friends who have.
Don't know how I've escaped. But have heard the stories of cops, medics and firemen. Friends of mine.
You don't want to go there. It's amazing how paramedics are so blase about what they see.
I feel lucky. Last time a paramedic friend told me an amusing story of guy who fell on a chainsaw. Ha bloody ha! I wasn't so amused but I like the guy so played along.
