I fell 23 feet from a hang on stand back in 2005. I'd just gotten the stand strapped to tree, and stepped onto the platform and was fixing my safety belt to the tree when the strap gave way.
Somehow, I kept from landing on my head, and managed to land on my side. My buddy who was standing there watching said that I bounced up off the ground almost waist high. I don't know how it didn't break bones. It knocked the breath out of me and as I was gasping for air, I noticed that my friend's face was as white as a bedsheet. He got sick after seeing that fall and was nauseous thinking of how it could've turned out.
What it did do, was fix my neck that had been bothering me for years after a lady ran a stop sign and t-boned me. The neck pain was gone. Not the kind of chiropractic fix I was wanting, but it worked.
The buckle on the stand was bent, and being the old friction type, it wouldn't hold. Every stand I put up now has three ratchet straps minimum, and I'm hooked up before stepping onto them. So, no serious injury on that one, but I could barely walk for a few days.
A freak thing happened at Ft. Campbell while bow hunting the Old Clarksville Base. I stepped into a Honey Locust thorn, and it slid along my shin bone for an inch or so under the skin. My leg swelled to the point of scaring me, and I was sick for a few days.
