Thanks for the comments, guys, I appreciate the concern!
I'm totally fine, and I didn't post this for any purpose other than an FYI. I probably should have qualified that the quiver I was using only has one contact point with my belt, so if/when you do fall, the quiver is free to rotate around that single point of contact. My "fall" was the most basic type… walking down a steep slope, my right foot slid out from underneath me and before I could do anything about it I was on my butt. My head didn't have to go far because when I landed, the bottom of the quiver was pressed against the ground and the nock end of arrows were 30" above that. Not saying this would happen every time (or even most of the time) with a single contact hip quiver, but I'm almost 100% positive that this wouldn't have happened if my arrows were in a back or bow quiver... and that's what I'll be using for now on.
