As a child I had to lay on the ground once because of bullets flying over my head

 We were jack rabbit hunting in the desert near Red Rock Canyon then likely around 1957 or 1958 then. So, I would have likely be 9 or 10 years old. My cousins and I had gotten separated as they were 5 years older than I was running after rabbits then and they had turned around and were shooting at a running jackrabbit in the desert then but they were running towards me and couldn't see me because I was 1/2 mile to a mile away from them. I heard the bullets flying over my head so I was smart enough to lay on my belly on the ground because I didn't want to be hit accidentally by a .22 Long rifle cartridge because they couldn't see me yet even though I could see them and hear the bullets flying over my head from them shooting at the Jack rabbit. It was a strange feeling then at 9 or 10 having bullets flying over my head. 

The strangest thing about it was the buzzing sound like a bumble bee when the bullets whizzed over my head and then much later (because sound travels much slower) I heard the report of the guns.

When the armorer talks about not feeling secure in her abilities it takes a certain kind of methodical person and even though someone not methodical and mechanical enough to being a full armorer if you get the wrong type of mental frame of mind in a job like that it could be dangerous.

I was trained from about age 8 to think very methodically regarding guns but many people in the 1950s especially many girls and women were never taught to use guns simply because you needed to be in a certain frame of mind or you were and are dangerous to everyone if you held a loaded gun. So, unless one is methodical and mechanical in their thinking (very much where the rubber meets the road so to speak) they would be dangerous as an armorer on a movie set.

But, often people don't care about what keeps people alive these days like they did when I was growing up.

It's part of the infantilization of people since the 1970s and 1980s I believe.

When I grew up if you did things wrong with guns you might be beaten to death by those around you in that moment. So, you always were scared enough to be safe or you knew you might die soon.

It was a much more scary time to be alive and yet you also learned (if you survived it all) how to act and to be so you stayed alive too.
