I find that the way I carry myself helps me in everyday life. I walk confidently..some say I walk too fast. More confident people, meaning more situationally aware people, act differently. I'd think more inexperienced potential perps would find an easier target. Surroundings being as they are, I constantly look around me..quickly scanning first near, then again further out. Perhaps I'm overthinking it, but I've been doing that 40+ yrs. Works for me.
