KD, Sorry to hear about your fall. A concussion and broken scapula are not exactly minor injuries. Glad to hear that it wasn't worse and hope your recover quickly. We don't bounce as well as we used to.
Concussions can be a scary thing. My wife had a bad one from a head-on car accident many years ago that led to partial amnesia. It affected her short term memory from just before the accident up to the present moment in time so she would keep asking the same questions over and over like she was stuck in a loop. The amnesia subsided, but she still has no recollection of the accident or events that happened immediately after whereas I remember it all clearly. Similarly, I had a bad ATV crash, a 3-wheeler no less, in my careless youth that led to a double compound fracture of my lower leg. No concussion that I know of, but my mind blanked out the moment of impact even though I remember everything just prior to and immediately after the crash. It's the mind's way of protecting you from the trauma.
I spent many of my college breaks working for a friends roofing company to make some cash to pay my way through school and have always been sure-footed so working on ladders or roofs never bothered me. Like you and many others here, I'm Mr. Fix-It at home, but the concrete barrel tile roof on our current house is another story. It's a steeper pitch than most I've been on before, the S-shaped barrel tiles are hard to walk on since they're not flat, any built up dirt makes them slippery when wet and the tiles don't feel stable - like the one I'm stepping on could break at any moment and send me skidding off the roof. I have been up on it for a few simple repairs and inspections, but didn't feel as comfortable as I'm used to so more recently we've been paying someone else to clean it every couple of years or make repairs when needed since I figure that the cost of the hospital/Dr. bills if I fall off will be more than paying someone else.
