Cept again, that's not how it works in a real world, right?
All I can say, Remathilis, is that your conception of the "real world" is far different from mine.
In my "real world", there are cities, neighbourhoods, etc., where getting shot is much more likely than in others. I've had a gun pointed at my twice in my life -- once by an officer of the law (honest mistake on his part!), and once by a guy in a bar in California. Neither time, strangely enough, did I get shot in the head.
I used to work in "Boys in the Hood" country in Los Angeles (the Kraft Knudsen factory at Slauson & Crenshaw), where they included tie and suit jacket/sweater in the dress code. I am white. Every day, I took the bus into and out of work, and almost everyday I walked to get lunch in the neighbourhood. I had a problem once with two fellows who were drunk, and it was a problem that was dealt with without violence, flight, or anything other than words.
I once fell 35 feet and broke my back in four places (L1, L2, L3, and L4), and was told that I was never going to walk again without a cane. Well, that turned out to be a false prediction. I now go hiking every summer. It hurt a lot (at times) to get to that point, but I was glad that I did.
I have seen two tornados first hand, once as a child and once as an adult. I have once seen the aftermath of a tornado I didn't see. Oddly enough, I wasn't harmed in either instance (although the first one was certainly scary!).
I have lived 42 years now, and so far as I can tell have never been struck by lightning or gotten an incurable disease. Although I've hiked all my life in country where there were dangerous animals (venomous snakes and/or bears at least, sometimes where there were wolves or cougars), I've never been attacked by one.
I have had friends die....the first of a congenital heart disease when I was in high school.....but I've never seen real people die in anything like the numbers that PCs and NPCs do in most D&D games.
If anything, the sandbox world is considerably more dangerous than the real world, with considerably greater chance for a "sucks to be you" moment.
