answer:I exercise every morning by power walking 2 miles. This is before sunrise. I know my senses are heightened when I’m on the street and see another person. It’s dark, so I spend some time guessing their gender. In my situation, the men would rank higher in the threat level. I also spend some time guessing what they are doing and watch their body language. I am happy to report I have never once encountered danger. Even the homeless people I pass by are harmless. In fact, they are the friendliest. I am not sure exactly what my inner dialogue is like at these chance meetings, but I have one. I’m fairly certain I’m trying to determine my ability to defend myself, but that’s honestly all below the level of conscious thought. At the front of my mind, I’m usually deciding whether or not to greet the person. We’re friendly here, so speaking to strangers in the wee hours is not uncommon.
