Be careful Rob. There are more important things later in life than riding... like walking! And not being in constant pain. I can't tell you all the ways my horses have injured me (but nothing as catastrophic as your pelvis break). I once almost lost two fingers in a loading accident with a skittish, fearful big brute of a horse. Big Red. We don't keep any horses now, but I do love them.
Glad to hear of your improvement!
