People were quicker to violence in the Wild West days because everyone was struggling with the effects of cumulative CTE brought on by brain-rattling horse-based transport on roadless surfaces
A single mildly bumpy ride won't turn you into an NFL domestic abuser, but over the course of 20+ years? And if you were on horses or in rickety carts from the time you were a squishy infant? Boom, curdled grey matter.
No horses = no war, no murder, just pure enlightenment and peace on Earth.
that's not quite how that works. even at a gallop, you're more moving with the horse than being rattled by it, and carts/carriages/etc. had suspensions to make the ride smooth (mostly for the rougher, unpaved roads).
even then, CTE is believed to be caused by multiple, sustained impacts/shocks of a magnitude greater than what one would experience while riding a horse. speaking from personal experience, none of my horse-riding (or even carriage- or cart-riding) ever came close to being hit by an NFL lineman at full-speed or being on a bombing range.
Clearly, you’ve never headed a ball in soccer. That’s quite a good bonk on the noggin, and still nothing close to riding a horse— which, I feel needs adding at this point: you don’t ride a horse with your head.
But now I’m reminded of back in the 90s before they banned the flip-throw and kids were breaking their necks trying it.
I played quite a bit of soccer back in the day, yes. It's nowhere near the forces of a clash in the NFL, which is what was being mentioned as a typical example of what can give someone a concussion. All I'm saying is that it takes less force than many probably think. I'm not saying riding a horse gives you a concussion.
