 to increase the safety margin for myself and my family. I don't care anymore. I'm not worried about being embarrassed or offending somebody. If somebody's walking up to me and I don't like their looks, I don't mind yelling at the top of my voice, Stop right there! Oh, wow. Really, Tommy? Yes, really. Yeah, I'll do that. I carry a tourniquet because somebody might be bleeding out at some point. Remember my family? Myself? Never know.
