I think its funny that there are people that live in a neighborhood like this one below:
That live in some mortal fear of some sort of home invasion and thus arm themselves to the teeth against it.... despite the odds of such a thing happening to them in that kind of a community being astronomically small. Yet they might smoke, eat poorly, or not exercise regularly, and thus practically insure they will not live as long as they otherwise would have. And or they allow their kids to eat poorly and become overweight or obese, and thus practically insure that their kids will not live as long as they otherwise would have.
I say this as a gun owner and I am pro-gun, but it has been my experience though that those that are armed to the teeth because of some irrational fear of being raped or murdered by armed gangs in their home are usually some of the worst judges of actual risk out there.
