I don’t know if my advice proved helpful.
Nevertheless, the incident suggests that poor people who live in dangerous neighborhoods may be overweight or obese, in part, because they are denied the opportunity to engage in the simplest form of exercise: walking. (Though, if they have transportation, they could drive to a mall or other safe public area to do their walking.)
And, of course, the danger isn’t just from people. A person living in my area, who was walking his dog, was attacked by a pit bull terrier somebody had let run loose.
