It's pretty amazing to watch a bleeding wound quickly "knit" together with cyanoacrylate glue. Even cooler is to watch someone practiced at it work through the blood, looks like it's never going to work when suddenly, the bleeding simply stops and the wound edges are bound together.
I have a daughter. I tell her, "911 is what you dial after you're raped. 1911 is what you should have before they try."
