At least in my "community" it shows probably a decent instinctive understanding of the relative risks. I don't have one friend in the last five years who has been a victim of a violent crime. I have CLIENTS who have been, but they are doing things my friends would not do, shall we say. People in my "community" die of heart attacks and cancer. So they take steps to be more healthy. So honestly, I think people react to things which are actually happening to them and people they know. I wouldn't recommend anyone in the local community I know take up "self-defense" to fight bad guys. I would recommend they do it to fight heart disease. And "self-defense" for me doesn't mean what it does for a lot of people here. My best self-defense technique is conflict avoidance. Some may call me a *****.
