Being serious for a second that's entirely what my advice to do a "life audit" is all about. We all belong to certain demographics with varying degrees of risk of violence in our lives (and other forms of harm). And then overlaid on that we have our own particular lifestyles, jobs, choices and habits that can increase or decrease those risks. Normally, as we age, our risk of violence goes down. Less going out, less time out on the lash, less risky behaviour, less ego about trivial slights or arguments, more awareness of the repercussions of being in a violent encounter (physical and emotional), more awareness of the signs of violence about to kick off, more time with good friends and family and less time with casual acquaintances, more things we value and don't want to lose through being stupid, less kebabs at 3am, etc. But if you decide to get a new career as a prison officer or a bouncer in your mid 40's then your risk is gonna go up.
