Sticks,
My own life experience is my own.
Others are their own.
And then there are professionals paid to risk their lives such as LEOs, military, 'security' personnel.
As based on my own life experiences in total as to current, my own 'comfort zone' as you define it varies greatly as based on conditions.
Many multiple conditions.
Am I alone? [Best case scenario. I can take care of me and I know how I will act and react under conditions. No surprises. I know from past experiences that when all else fails I can absolutely depend on me, myself, and I. I trust me more than anyone.]
Where am I? [Location and environmental conditions]
Who am I with? [Wife who is slow off the X and is by nature and life view non-violent in belief, kids who are small aged 6 and 3 and thus cannot evac effectively on their own as individuals, or am I with an adult male or female...]
What clothing am I wearing? [Street clothes or business wear such as as suit which is more difficult to fight in.]
What shoes am I wearing? [Much more difficult to evac/run in dress shoes. I learned this lesson directly per past experience.]
Am I wearing glasses or contacts? [I wear my glasses most often to work events and business meetings. Otherwise I'm in contacts. I know from experience that glasses are a weakness that is easy to exploit and quite effective. I've learned the hard way and painful way to protect and defend that weakness with stand off distance.]
What is my physical condition at the moment? [Full belly or empty belly optimal. Feeling 100% or under the weather. Am I simply just not in the mood today/at the moment for no mess (!) or am I feeling jovial happy go lucky. Mood directly affects decision making and by that threat analysis and skill in doing so, with accuracy. Again past experience direct as well as by direct observation of others who won and/or lost.]
I could go on but bottom line it's a long and wide list of IF/THEN and AND/OR conditional items that make up the whole of my own program of sorts.
For example again as be learned experience and now ingrained habit, when ever I walk out of ANY door way as into a public area I will notably stop what I'm doing and scan 280 degrees. I do this if I am talking with someone in the immediate or whatever. I will stop to eye glance and head move to check typically my left side first followed immediately with a head move scan to my right followed by a forward arc scan.
I learned the hard way to do this as going back to K-12 in school for being jumped or getting the jump on others. Prey or be prey, and pray.
Same learned by observation on the streets. To which now is hard wired to my brain. I don't think I could undo it now even if I had desire to try.
This though does draw attention every so often from persons with me including my wife who thinks I am just flat out odd/weird as well as others who me who might ask; "Were you looking for something?". My general canned response to that has been "Nope, nothing at all."
Truthfully I don't have a comfort zone.
Am I perpetually uncomfortable?
My wife would say yes. My kids would say 'Huh?'. I say not, not at all.
Having no comfort zone is for me to my own view and life experience, a comfort. It is my normal.
Does that make me paranoid?
Nope, not at all. Just aware and observant of my surroundings.
I haven't had a direct danger situation occur to me in roughly 4 yrs. But I have no logical reason as based on past experiences to believe that as much would be my last in life.
Nosa mentions an item as a tag along called 'personal space'.
I am again by life experience stingy and protective of my personal space.
I actively maintain distance from people to a degree that I don't even think of it anymore, except for when persons of any gender goes beyond my comfort zone.
That for me is an arm lengths distance. My arms are ~32" in length.
In general as to strangers and people I know by name but not well, I am not comfortable with them being within my own personal space as at arms length.
It happens a lot though and isn't always avoidable. That's life.
But I do consciously detect when it happens a little thought flag pops up in my mindseye of this person is "close".
To which as based on conditions I'll either supress the thought or act on it as following my life experience based IF/THEN and AND/OR conditional act/react programming.
Basically as with any being (man or animal) who I see or condition I have enough sense to become a concern, I will as a general rule remove myself from that situation.
I used to be a stand and fight kind of guy. No more. I know what I'm made of.
Besides I've got kids and responsibilities and hopefully another day of life to live.
No longer interested in seeking out trouble or taking on a challenge as simply for the challenge of it.
I've got other stuff to do and think about like getting home in time for dinner with my kids to hear about how their day went down.
