Zooming by from the doctor-and-master members posts page, FYI.

The first time I a came on an accident scene where there were major, major injuries involved (not wristing-slashing as you describe; I hope the poor fellow gets the help he needs), I could not believe the amount of blood that was everywhere. It was an overturned car on a tight curve, and the driver (who didn't look alive) was half out of his window with what looked like a river of blood puddling under his head that was on the pavement. My S.O. (who has more experience of blood than I ever will) told me this was normal. Weird to see, though.
