I painted houses for about three years when I was in college; I'm very fortunate, having ridden down the side of a house a few times with no injuries to speak of. My only injury (other than sunburn and a burned bun from a thinner soaked rag) was the result of my own stupidity. For reasons I can't recall, I decided to stand on a sawhorse inside of a house instead of using a ladder. Stepping down off the sawhorse, I sprained my ankle big time.
You were a lot younger then. Somewhere between the Clinton and Bush eras somebody decided to turn up the force of gravity... while also making the ground a lot harder.
In my line of work you just expect to fall down; an aspect of constantly walking on uneven ground through bushes, often not even seeing where you put your feet. Then there's snowshoeing through the same terrain... I'm finding it harder and harder to control my falls. Rather than a graceful tumble, one second I'll be walking along, the next I'm down for the count. My body's too young to look like this.
