In a car, I wear a seat belt, and the car has air bags. I have never needed either to save my life, but I still use the seat belt.
Surprisingly, I have not had a need to use my trail first aid kit in over 20 years, but if I get injured, I carry a kit to mitigate the risk of further serious injury.
When stealth camping with a buddy, I leave the hardware at home, but there is increased risk when solo and far away from the busy trail crowds."

The point I was making about the helmet was that it was extra protection. People still get killed from head injuries in car wrecks even with seat belts and air bags. If you're trying to minimize your odds of being killed, a helmet in a car is a better bet than a gun in the backcountry.
That is surprising about the first aid kit. I used mine on Saturday for myself (got pretty scraped up) and on Sunday for somebody else.
Most of my trips are solo. I don't change anything either way. And I don't feel any more vulnerable than going with others. (Actually, I don't feel vulnerable at all.) I still bring my normal kit when going with others and I don't add a gun when going alone. I just don't see the need here in Colorado. But I didn't when I lived in SoCal either. I do see people with bear spray and bear bells occasionally here. When I ask where they're from, they're never from Colorado. They're on vacation and they've heard where there are bears you need that stuff. But you don't here.
The scariest animal I've encountered recently was a squirrel in Zion last weekend. We were on a paved trail after coming out of the Narrows and he was running along with a lollipop in his mouth. Still in the wrapper. It took 2 of us to take it away from him using walking sticks. He was p!ssed! Kept looking over my shoulder to make sure the little bugger didn't run up behind me and bite me in the ankle. Give me Bubonic Plague or something.
Now if somebody comes up with some portable, lightweight, lightning protection, THAT I'll carry!
Bottom line for me is: Whatever works for you. It's your kit.
