I'm not a doctor but I was EMS for a few years and one day we came up on an accident on the highway involving a motor cyclist and a minivan, usually that is not good, at all...it's always a mess.. We get there and find out he hit the minivan at 80 MPH while it was stopped on the side of the road and flew through the back window, through to the front and survived without a scratch on him, no broken bone no AMS (altered mental status aka blunt head trauma)... he even got himself out the van and asked if the people inside were okay. He was wearing a helmet and I think that saved his life.
Blew my mind.
