Here goes....
I fell out of a tree in the Manistee National Forest, while bow hunting, back in the late 70s. BC - Before Climbers. I'd just climb a tree and stand on a branch with my bow in hand, after pulling it up with a piece of twine.
Just finished working an 8 hour shift, from midnight to 8 a.m., then drove 7+ hours to hunt west of Cadillac, Michigan in the previously mentioned Forest. I'd been awake for over 26 hours and attempted to finish off the day by getting in some bow hunting, a couple of hours before dark.
The fall breeze felt good in my face, then the wind got knocked out of me. That "breeze" was the wind in my face, while falling out and landing flat on my back.
The sandy soil and fresh leaves cushioned my fall....a bit. As I sat up, regained my balance, caught my breath and realized what had happened, I made a decision to go back to camp and sleep it off.
